Some Thinkpads with Radeon video cards have a suspend issue that requires loading the radeonfb kernel module in the initrd. When this happens, the radeon xorg driver refuses to display at any resolution other than 640x480. Everything works normally (except for the suspend problem) when the radeonfb is not loaded.
Anyone else seeing this? Any solution? Is it an xorg bug or a kernel bug?
TIA.

No problem on my T30 (Mobility 7500). But feel free to file a bug upstream at bugzilla.freedesktop.org...

I get 800x600 as well on a R51 but nothing higher.
TIA.

Take a look at this bugzilla, perhaps one of the solutions in there will work (MergedFB off?).

Actually found the solution, which is posted here: http://www.ces.clemson.edu/linux/fc6_setup.shtml#radeon
Add |Option "MergedFB" "Off"| to the video card's Device section of xorg.conf.
