Hey all, I know I am late joining in this bug but I have been following closely. Running Ubuntu 10.04. Using workaround G from hforzman above. System runs a lot longer but now instead of the horizontal bars/zebra lockup... I get a black screen freeze.

I am subscribed now to the bug, and will work with all of you to help test on my end. Let me know what I can do --- even though I am not the most experienced. I am going to try Brian Rogers' fix and see what happens.
