This bug was fixed for me with the patch for bug #492392. (Which disables powersave for i915)
There is no flicker and it runs stable for hours.

I tried out linux 2.6.33-020633rc5-generic from the kernel-ppa with i915.lvds_downclock=0.
There was no flicker but it crashed (gray screen, but still able to login via ssh) after a few minutes, this time though I was able to get a batchbuffer dump.
