I am not sure whether the problem I am having is not the very same as
the one Arkadiusz is seeing. At least I've found resume from s2ram to be
working a couple of times. Only sometimes it took long to resume, that
is >30 seconds (around 5 - which I already consider long - is normal). 

anyway this this is with the closed source fglrx kernel module, as
without the machine freezes when X is running on resume...

well and fglrx seems to cause this ...

Arkadiusz, are you using any of these binary crap modules?
