Yes,
the initial bug with the graphic system was solved in the meanwhile.

However I tested the current git kernel v2.6.35-rc6-156-gfc0f5ac with a stable 
Gentoo (nonetwork, only minimal system services started) and could s2ram it 
many times in a row using the echo command.
But as sson as I used pm-suspend then after the 3rd or 4th attempt s2ram hangs 
with the blinking moon led. The command I used were
$>sudo -c "export PM_DEBUG="true; pm-suspend"
and
$>"sudo su -c "echo mem > /sys/power/state"
respectively.

But there's nothing in the log :

tfoerste at n22 ~/devel/linux-2.6 $ tail /var/log/pm-suspend.log 
+ is_set true
+ case ${1-UNSET} in
+ return 0
+ local 'fmt=%s\n'
+ '[' 'Wed Jul 28 22:30:30 CEST 2010: performing suspend' = -n ']'
+ printf '%s\n' 'Wed Jul 28 22:30:30 CEST 2010: performing suspend'
Wed Jul 28 22:30:30 CEST 2010: performing suspend
+ sync
+ do_suspend
+ echo -n mem


:-(
