If anything, I would hazard a quess that having LR and your photos on two different disks might actually speed up LR. The operating system's disk I/O would then be on one drive, separated from LR's disk I/O on the other drive with the photos. LR's doing a lot of processing to get an image to update and display with the current set of edits, so that's going to tax memory and CPU to some degree.
My LR 2.0 installation under XP Pro x64 seems to be noticeably zippier when it comes to displaying previews. It looks about as fast as some Mac laptops that I have seen working in demonstrations.
Still, LR 2.0 x64 edition seems to be noticeably more responsive. I haven't imported any photos yet though, so that will be another test that I'll get to do in due course. I'm hoping to be pleasantly surprised.

Only time will tell...
