Can't put laptop to sleep any more

OK, last post in the current batch.

Since my last updates, I can't seem to get my laptop to suspend
any more, neither to disk or to RAM. Before I just used
"acpitool -s" to put it to sleep and "hibernate", but now both
of the commands initialize the process (i.e. switch to the console)
but then obviously hang. I waited several minutes before I then
had to hard reboot the machine.

I don't get any output of hibernate in /var/log/messages but it
writes something to screen like the usual "Freezing processes & syncing
filesystems, stopping tasks" etc. before it hangs. Writing to disk
is obviously never initiated as the disk light stays off.
For acpitool -s I just get
Oct 25 18:57:14 schnurps PM: Preparing system for mem sleep
in /var/log/messages just as it always did when it still worked.

I'm still running kernel built from suspend2-sources-2.6.22-r1,
the same as when it was still working. As a first try to get it
working, I also updated
acpitool-0.2.7 --> acpitool-0.4.7-r1
hibernate-script-1.96 --> hibernate-script-1.96-r1
but that didn't help. I output epm -qa of a working and the
broken condition and append that below, in case that reminds
someone of something.

Thanks in advance for any idea,
Peter.

Found the solution myself today. The fglrx kernel module keeps
the system from suspending. Calling modprobe -r fglrx in my scripts
before the actual acpitool or hibernate command help.
