Fine for you that you have the time for this new/regression preconfigured
modeline nonsense. In over 100 installs over at least the past five years, on
Fedora, Kubuntu, openSUSE, Knoppix & Mandriva, never until now have any of my
xorg.conf files needed modelines in order to make supported modes available.
Always some part of Xorg or the drivers it depends on was able to manage
without preconfigured modelines, for all I know, calling cvt on the fly to do
the work.

FWIW, I do now have the 845G with F13 running 2048x1536, but the amount of
work required to set it up is just nuts compared to how automatic it was
before auto configuration development "progressed" up to now. The xorg.conf
and Xorg.0.log resulting:
