I have more or less the same problem. I have a Pc, not a laptop, with Ubuntu 8.10, Radeon X600. In my computer too, the monitor has a problem in mantaining brightness stability. It randomly changes in the first 10 minutes of activity of the computer, going down. I attach the lspci output and the Xorg.0.log.
