Guys, he's needing direct access to his sound hardware. A VM is going to fail here.
I'd use Boot Camp with 32-bit Vista if you want the best possible experience. XP works, but you can't use dual screens if you've got an external monitor. 64-bit Vista sort of works, but you have to really work at it and forget about your iSight camera; dual-screens works. You'll just run the BC assistant, which will let you partition the drive, reboot with your Vista disc in the drive, and after Windows is installed you'll install drivers and the Windows side of Boot Camp from your OSX disc. Easy peasy. It'll be formatted as whichever filesystem you tell Windows to use (NTFS unless you're insane). After this you can hold down ALT upon reboot to choose which operating system to boot into. If you hear the BONG it's almost too late.
Putting on Linux after this is dicey. Ubuntu made some change or another to the MBR equivalent that slightly borked Boot Camp, in that after that the BC assistant could no longer edit the partition table and the Windows partition was no longer hidden in the Finder, but everything continued to boot OK. This even happened when I used Wubi.
ISTR that Vista SP2 (if you've got a disc with that pre-integrated) groks EFI firmware, so you might be able to just install Vista directly without messing with Boot Camp; you may need to boot from your OSX disc and pre-partition the drive first, then reinstall OSX. I haven't done this, so I don't have any pointers. Here be dragons.
 from my experience with a Macbook 2,1 with 945 chipset and OSX 10.4 & 10.5. No idea if this was fixed with later models.
