I don't know.  I've no plans to downgrade from 10.6.

If it works with 10.6, and there's a driver for the same card in 10.7,
it's very unlikely that it won't work.  Once you've booted the OS, you're
past the need for Mac-specific firmware.  It's all PCI IDs and drivers
from there.

I had the same thing happen with the ATI x1900xt in my Mac Pro.  The
screen corruption was pretty impressive.

Yeah, it's some combination of Apple mark-up, tiny target market, and
support costs.  The end result is sad, but if PCs would ditch BIOS for EFI
(finally), this situation could quickly reverse itself.
