Actually, I have an XP install on another drive, just need to fix the MBR to actually boot it.
Try that this week, let you know how that works out. Everything else like loadout screen worked fine (no AA used though), just didn't get proper graphics in mission; I'll try some troubleshooting as well, might get it to work by disabling desktop composition (shut down that aero theme stuff from Vista/Win7 temporarily).
