Partial fix

Ok, here's a partial fix, the other part being something wrong with scaling
modes which I don't presently understand.  To test the fix, apply the patch,
and to work-around the scaling problem add `Option "ScalingMode" "panel"' to
the device section of your xorg.conf ("noscale" should work as well as panel,
"aspect" and "fullscreen" won't).

Assuming this works and you feel like a new challenge, if booting with the
monitor on the other dvi port gets an image with randr12 turned off (or even
with the "nv" driver), feel free to make comparison regdumps of that and we can
look at fixing it for randr12 :-)
