[vfio-users] Code 43 for GTX 660

[Philip Abernethy]

They're only in there so I get a higher resolution. 640x480 is kinda
tedious. Some of the installer windows from the nvidia driver have ads
nearly that big, that block the buttons. But the problem persists without
spice output, too. I'll try the wrapper script francesco suggested.
