Since this effects only the guest driver, and then only the guest
driver for one platform, this really should not be handled through qemu
and the rom at all IMHO. Guest driver options should use whatever is
the common mechanism in that platform to set driver options, so in
this case xorg.conf.

ROM based tricks and the likes are for things like advertising hardware
/ client capabilities to the guest driver, not for things which can be
handled purely inside the guest.
