Ok, I guess one more pair of eyes would help.

(list of 20 bugs in redhat bugzilla).

...well, it looks a bit better from my side. Number of suspend bugs in
suse bugzilla is certainly lower, and I guess it works a bit better,
too. (But we do not claim s2ram support for machines outside of s2ram
whitelist).

Now, perhaps redhat should get someone to work on suspend/hibernation
support (kernel level)? IIRC you had Nigel at one point, but he was
working on something else?

Rafael and me am trying to look after hibernation, but I believe noone
is really working on suspend :-(.
