Comment 20 for bug 555595

I can't see any way -18 could be ok and -19 bring up this issue at all at least from the drm side. Virgil, can you please try a few mainline kernels without updating any userspace components in between and see if they can reproduce it?

This one should not exhibit the slowdown problem if it is really a problem in the kernel drm:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33.1-lucid/

And additionally If this one works, it would point the finger at a ubuntu specific patch:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.12.3-lucid/

Thank you for the help!
