Can you attach the output of xrandr --verbose from Maverick when it's working. I'd like to see the /var/log/Xorg.0.log from that case as well.
Also, on natty please turn on drm debugging. You can do this using the xdiagnose utility, it's the first checkbox in the dialog. Reboot and then reproduce the bug, and then run 'dmesg > dmesg.txt' and attach it to this bug report.
