Yes.

The linux kms drivers simply use the kernel's mode database, to provide
a list of standard resolutions. Additionally you also can define your
own resolutions, using xrandr --newmode & --addmode).
If we want go beyond passing a simple "please use <width>y<height>" we
probably should generate a edid block and pass that to the guest, but I
don't see a strong reason to do so.
cheers,
Gerd
