Works pretty good for me. I did run into the fuzzy screen problem. I use to
be able to work around that by switching between X and the console a few
times. With the patch that didn't seem to work, but putting it to sleep did fix the
problem. Waking up in X had an intial low-res like screen with some broken images,
but it did correct itself after a second.
