Well, perfect knowledge is a necessary but not sufficient condition for this discussion. If god were just omnipotent, but was not all knowing, I believe you could still argue freewill exists.
So it's not just knowledge, but perfect knowledge?
What if God doesn't have perfect knowledge (ie, he can't know anything about our past), but he does know our future? Would that also destroy free will in your mind?
What makes the knowledge perfect? Lets first take the idea of imperfect knowledge. Lets say God somehow has full imperfect knowledge. That sounds sort of silly. But lets say God has an opinion about everything possible, however his opinions are all wrong. That's what I'm considering to be "full imperfect knowledge". God has no doubts about everything, but in fact he is wrong on everything. Lets take an event about tomorrow for example. God fully believes that Bob will eat pizza tomorrow for lunch. And what do you know, Bob eats a taco instead. If this happens, then we can say that God's knowledge of the event is incorrect. However, if Bob does eat a pizza tomorrow for lunch, then God's knowledge becomes correct. In short, it seems to be not somehow just having knowledge itself that makes it correct, but the knowledge is only correct if it corresponds with reality.
Knowledge can be correct or incorrect.
Knowledge is only correct if it corresponds with reality.
If God has knowledge of an event, his knowlege can only correct if that event corresponds with reality.
If God has knowledge of an event in the future, his knowledge will only be correct if the event actually happens.
There really is no argument against free will. Omniscience doesn't change the possibility of free will. Omnipotence doesn't change the possibility -- in fact omnipotence almost logically gaurantees free will and the ability to create other creatures that have free will.
For this brief argument, I'll assume:
"Free will" basically means being the root cause of one's own actions.
And a "free creature" is something that has free will.
P1. Either it's possible or impossible for a creature to have free will.
P2. If it's not possible for a creature/thing to have free will, then there must be an infinite regression of cause/effect and it's impossible to have a beginning.
P3. If it is possible for at for a creature to have free will and that creature is the first or uncaused creature, then there can be a beginning.
P4. There was a beginning.
P5. If at least 1 creature has free will, then it is possible for a creature to have free will. (blantatly obvious, huh!

)
C1. Therefore, the first uncaused creature necessarily has free will.
C2. It is possible for a creature to have free will.
The only arguable premise here that I see is premise #4. You can either suggest there is a beginning or there is not a beginning or you can say there isn't enough information. However, the big bang points to at least a beginning for the universe. The philosophical problem with an infinite regression of cause/effect point to a beginning. But if you don't buy into either of those ideas, we can still apply occam's razor and say that it's much simpler & sufficient to suggest a beginning than an infinite extra causes and effects.
But regardless, you're left with either asserting a personal opinion that there is no beginning or you're left with simply asserting that not even a God could have free will.
P1. Either it's possible or not possible for a free creature to create other free creatures.
P2. If it's not possible to create creatures that are free, then God cannot create people with free will.
P3. If it's possible to create creatures that are free, then God could create humans that have free will.
P4. An omnipotent God can do all things that are possible.
P5. It's possible to create free creatures.
P6. God is omnipotent.
C. Therefore, God can creature people with free will.
Hmm... I could have probably reworded those arguments a bit better, but I'm pretty whiped out today.
The thing that strikes me is I keep hearing folks say that not that their simply asserting their personal opinion that there can be no such thing as free will, but they state that it's a logical impossibility. And yet no one was offered a sound logical argument to show that it's impossible.
