This bug also effects Toshiba A215 series laptops. Jens Janssen's work around of running at 1.6ghz or higher CPU clock also can be confirmed. So it would seem to be an issue with memory timing at the lower clock frequency since the x1250 uses system ram instead of dedicated. I am willing to

The second fix Jens posted seems to work pretty well, though the flickering is still there. I'd say this is a pretty big bug, considering that with the removal of support for so many legacy ATI cards, especially the x1200 and x1250, from the fglrx drivers, there will be thousands of users

This bug seems to be a bandwidth problem. When set to 800MHz the DRAM frequency is at 160MHz. Everything above 800MHz sets DRAM frequency to 320MHz (see http://www.linux-phc.org/viewtopic.php?f=6t=46). So here is my little workaround: Install sysfsutils. Then edit /etc/sysfs.conf:
