Wow, my comment got lost when I filed the bug. Awesome.
Anyway, this ppc64 system has a Matrox graphics card:
0001:02:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G550 AGP
^-- possibly interesting non-zero PCI domain
The mga driver claims to support the G550, but Xorg isn't using the mga driver for some reason:
[ 149.468] (**) FBDEV(0): claimed PCI slot 2@1:0:0
But as it turns out, the install was done with 'usefbx', which is equivalent to 'xdriver=fbdev', and when you use 'xdriver' anaconda will write /etc/X11/xorg.conf to force that driver into use. Hence fbdev instead of mga.
