(II) RADEON(0): Panel ID string: IBM J1838 ITSX95

(Unfortunately I have no external monitor to test.)

Laptop runs Ubuntu 8.10/Intrepid, Linux kernels 2.6.27-14, 2.6.27-11, and
2.6.27-7 available. Can dual boot Windows XP SP3. Problem has not been seen to
originate when running Windows. Some residual corruption has been observed to
persist after a soft reboot (reboot without powering down), however.

xorg.conf is all defaults, set by Ubuntu (Debian?) installer.

Problem observed with radeon driver 6.9.0 provided by Ubuntu 8.10 package.
Still present in radeon_drv.so 6.12.2 and git master as of 2009-06-12.

(This bug report split off from 21553.)
