xrandr --verbose output (with monitor connected and working)

Whenever I plug an external analog (VGA) monitor to my 12 inches Apple
powerbook I can see with xrandr that it is correctly recognized. When I turn it
on with xrandr --auto my desktop appears on the external monitor (mirroring) in
full height (768), but on the left the first 290 or so pixels out of 1024 are
black and the same happens to the last 16 on the right. This same behavior
happens with two different monitors.
Image quality is excellent and there's no distortion or stretching whatsoever,
the pixels are just plainly black. To give an ascii-art idea:

xxxxxooooooooooox
xxxxxooooooooooox
xxxxxooooooooooox
xxxxxooooooooooox
xxxxxooooooooooox
xxxxxooooooooooox

x are black, o are ok (proportions are of course not respected :))

Trying to change the resolution doesn't give a different behavior. I'm
attaching a xorg.log and the output of xrandr --verbose

This happens with git head for both ddx and drm, xorg server
1.4.1~git20080131-1 (debian package) and libxrandr2 1.2.2-1 on debian lenny ppc
