The above looks very much like the issue that made me write commit 45171002b01b ("radeon: add AGPMode 1 quirk for RV250"). See https://bugzilla.redhat.com/show_bug.cgi?id=531825 for a lot of background.
Does booting with radeon.agpmode=1 survive a suspend and resume cycle?
Yes, that option helps. Thanks!
Then I suggest you add another quirk for your T40p (after testing agpmode 2 also). Because this all seems to be caused by a broken BIOS, and/or broken AGP thingy, and/or broken RV250 (or the interaction of these things or whatever). Maddening stuff, impossible to debug.
Good luck,
