reconstructing xorg.conf from memory (on another machine not booted and i gotta run out the house):
Section "Device"
Identifier "Builtin Default intel device 0"
# I stole the identifier from Xorg.0.conf run with no xorg.conf
Driver "intel"
Option "ForceEnablePipeA" "True"
EndSection
...and that's it; everything else is autodetected. for thoroughness sake, i ought to test without it, but i haven't yet.
also, it's a driver bug. drivers are part of the kernel, but also their own separate projects.
