I can confirm this bug with Maverick and Lucid on Thinkpad T60 / radeon X1300. Trying modeset/pll parameters, but it seems like random problems related to firmware in the radeon card, memory layout of the machine or something else. (I have two T60, one with 3GB and 64bit, the other one with 2GB and 32bit. One has the problem only with external VGA display, the other one (2GB/32bit) has the problem on the internal screen as well.) Both run the latest BIOS from Lenovo - Lenovo doesn't provide ATI firmware updates. Sometimes the flickering starts after some time using the machine, but not related to temperature or load.
