Normally I use rivafb, but I tried video=ofonly and did not get a
freeze. I tried it three times and I hope that this is good statistics.
With 2.6.12-rc2 and riva fb I got the freeze in about 80% of all initial
suspends, with rc{4,5-git6} and riva fb I had it everytime. But it may
still well be that there is a random component since I learned to
workaround the problem by switching to tty1 and thus don't trigger the
freeze condition that often.Thanks, Wolfi
