Hi Alex, I postponed working on this issue for a while because I was not able to figure out how to permanently alter GRUB loader options. I broke down, and decided to insert radeon.agpmode=-1 everytime I boot for testing purposes. By the way, even after adding radeon.agpmode=-1, I still see random freezes and or instability with Radeon 9800 Pro. Looking at the dmesg.0.txt messages, I think my Radeon 9800 Pro is still being considered an AGP device despite adding the radeon.agpmode=-1 option in GRUB. Anyway, I added various log files related to power management to the bug report. Note the time jump between Oct 13 16:38, Oct 13 16:44, and Oct 13 16:49. I believe at one of those times, the computer froze (with a blank screen). You can take a look at it to see what is going on.
