Sorry, I got sidetracked and didn't get around to testing the patch,
I've now tested it and can report that it solves the problem of
windows 7 locking up on boot.

And performance is much better with viridian enabled, previously it
was quite laggy in both vnc and rdp even with nothing much running,
its noticeably better now.
