Things I noticed: The drivers CD that apple has you make doesn't work. It starts installing, gets to about where it starts installing various drivers, installs the video ones, and then goes stupid, rolls back the changes, and says it errored out. I haven't tried to extract the MSI that has the driver packages so that I can manually do it yet. Also I installed the ATI Beta vista drivers and even though they install fine I don't get glass and 3d stuff explodes in my face too. I thought I read somewhere that someone did get glass going but I haven't yet.
Anyway thats it for now. Still doing half a dozen things at once. I'll post more later as I figure things out. Here's some pics.
UPDATE: Just so people aren't confused by this old post I believe Vista RTM works with Bootcamp 1.1.2. If you don't have the latest version installed or for some reason I am wrong you also can just delete the 200MB EFI partition and it should also work without killing OSX. You'll just loose the ability to remove vista later. You also can install vista as the only OS assuming you don't want OSX.
IF YOU ARE INSTALLING VISTA.... I recommend seeing this thread as it has a good step by step walkthrough for the drivers
