It generally is, but I've had some fights with cards that aren't super new.

I was always able to get my 5850 to work until I installed gplpv,
which would give that BSOD. I'm told that's not an issue for anyone
these days, but I've only seen that on Windows 7 DomU's.

Also, sometimes, FLR-related issues will give that BSOD.  You could
try detaching the card, attempt a good boot, reboot dom0, reattach and
boot DomU.

Good luck!  YMMV, but I hope it helps :)

Cheers,
Andrew Bobulsky
