Fwiw, I've uploaded the final 6.12.0 today. I re-tested this on an hd4850 but did not find the whitescreen issue gone.
Can you two please update to today's latest (with -ati 6.12.0) and verify the white issue is still gone? If it has regressed please re-open this bug so I can explore further.
I also have a new -fglrx 8.60 which I've tested on the same card, and found it works great.
Glad to hear my git snapshots fixed the issue.
