Here's the status with -rc3: better, but still does not work as well as 2.6.20.

1. Switching to console VT, and running s2ram, I am able to resume to console
(I have not tested with echo mem > /sys/power/state yet, both work OK
with 2.6.20)
This seems to take about as long as with 2.6.20.
During this time, I see some messages on console (see attached log)

2. First disk access after resume takes a couple of minutes
(seemed instant with 2.6.20) during this time no new messages show on console

3. When I switch to X (CTRL-ALT-F7), X hangs after drawing a couple of windows
after waiting for some 10 min, I rebooted.
no new messages showed up in /var/log/messages

log attached
