The "patch" is that they use an xorg.conf and hard-code 1024x768 as
their default resolution.  We don't use an xorg.conf at all[1] in Fedora
and instead rely on the X server to be able to probe things.  Cirrus
hardware doesn't support any form of reasonable DDC and thus it goes
with its fallback which is 800x600.  Given that most of the hardware
which ends up using the fallback paths is old and that hardware is the
hardware most likely to have problems with > 800x600, it's not really
safe to change that.

because the driver is lame ;)
