I've had a working configuration for a few months now with a 4770.

However, this configuration lacks the VBIOS passthrough, so one needs to use 
VNC to install the drivers.  There is an old patch floating around that does 
ATI bios passthrough, but it  would need to be forward ported.  That being 
said, I never cared too much, since I can't use my passthrough'd USB keyboard 
to do anything in the guest until an OS loads with USB support.

Hmmm, actually, I wonder if seabios supports USB keyboards...
