BusID           "PCI:1:2:0"
in the "Device" section, but I don't have it in my xorg.conf
anymore.

Exactly the same as mine.

I don't have that in my xorg.conf and never did.

With this version of Xorg, X doesn't work here without an xorg.conf,
but it DOES WORK at low resolution (640x480?) with a zero-length
xorg.conf. I get better resolution when I put my monitor specs and
default depth of 16 in xorg.conf.
