Apple released an update to Boot Camp today for Windows not Leopard
The new version is 2.1 Build 210A12.

This is supposed to remedy some of the problems users are having.
Because I am already running Vista x64 with Apple 64 bit drivers I can't say if this will support x64 or not.

So far there seems to be no change, but I had almost zero problems before.

Strange but on the Canadian Apple site there is no reference to this update.
But Apple software updates installed it fine.

The size is "almost" 250 megs or somewhere around that.

I am running a iMac 24" Aluminum with 2.8 ghz Extreme processor.

Maybe this update will help others.

Well after installing the update on my MBP 17 running Vista x64 Ultimate now my Keyboard hotkeys don't work - The backlight controls, multimedia controls, etc... are non functional.

There is a discussion about this at the Apple site.

This may or may not help your problem.

Worth a read though.
