Ok, I have installed this kernel in a couple of places and am waiting to
see real world use. That said, I have a script that:

1. plays a 500M flv file in totem, in repeat mode
2. launches 'glxgears -geometry 1400x1050' (the native resolution of the display, but not full screen mode)
3. launches /usr/bin/gnome-*, firefox and oowriter one at a time, in a loop

This brings the system to a crawl, which is fine but with the updated kernel I get a bunch of messages like this in kern.log:
[ 2168.016130] radeon 0000:01:00.0: ec7c4600 reserve failed for wait

It wasn't until I added glxgears to the mix that these messages started
showing up every couple of seconds (prior to running glxgears it only
happened once). I booted back into the latest official lucid kernel and
ran the same script and saw those messages did not show up in kern.log.
The system seems otherwise fine (ie no crashes), but I don't know if
that message is purely informational or an indication of something going
wrong.

I can also say that with the latest official lucid kernel, the guest
session is completely unusable, though differently than from Vish in the
upstream bug. After upgrading to the patched lucid kernel, the guest
session is fully usable.
