Here is some more data for vfio-vga.
I have tried NVIDIA (MSI) GT610 and ATI (MSI) 7850 cards separately in primary and secondary (to Cirrus) modes. The ATI can boot as primary in VGA mode, but installing Catalyst causes the VM to reboot repeatedly on bootup. The NVIDIA doesn't get past POST as primary. Neither card works as a secondary with their drivers; they each complain that there aren't enough resources available (code 12) in Windows device manager.
I have tried a few different KVM device settings, but feel like I am poking in the dark at this point. What I am currently using is at the bottom of the e-mail. I have URLs pointing to the various compressed logs since they are fairly large. If there is any other data I can provide, please let me know, I would really like to get this working :).
Machine:
Motherboard: Intel DQ67SW (BIOS: WQ6710H.86A.0052.2011.0520.1802 05/20/2011)

Kernel: 3.9 - current vfio-vga-reset branch
Qemu: 1.4.50 - current vfio-vga-reset branch

Qemu has this patch added to vfio_ati_3c3_quirk_read():
+ if (1 || data == quirk->data.address_match) {
NVIDIA:
When it is primary, the NVIDIA card ends up with a QEMU fatal error within a couple seconds of startup (the EIP seems to vary slightly). I have seen this with 3 different NVidia cards (Quadro FX 580, GeForce 8800 GTS, and a brand new GT610):
qemu: fatal: Trying to execute code outside RAM or ROM at 0x00000000000a0000

ATI:
The ATI card is able to boot Windows in VGA mode once I add "if (1)" to the 3C3 quirk in QEMU. Once I install the Catalyst drivers and reboot, the machine reboots itself 10-15 seconds after the Windows boot loader finishes. I am not sure if it's blue screening and I am not seeing it -- there is no output.
