Please. This is a real bug. AND a solution is at hand, use it!

I compiled myself a new kernel with the latest patch from
http://bugzilla.kernel.org/show_bug.cgi?id=3022 which solves this. It applies
flawlessly to the kernels i tried. ubuntus 2.6.12 up to vanilla 2.6.14.

I can't see any trouble for Ubuntu kernel to simply include this patch.

The patch uses a whitelist for hardware known to work, the rest can try it out
by adding radeon_force_sleep=1 as a module option.
