Hi all,
I logged the solution of kernel 2.6.35-020635-generic having worked for me earlier.

I tried this "blacklisting" trick on kernel 2.6.38-10-generic (last update) and it worked only if you had NOTHING MORE than maybe a 'terminal' session active when you try to 'hibernate' (any more - Firefox with a few tabs open + Evolution <<--CRASH).

Otherwise it fails just like the original but the syslog shows:

I think it is much more than coincedence that many of the 'failed' lines above refer to 'firegl' and I believe that 'blacklisting' the 'firewire' entries is what causes it to fail.
Back to my '2.6.35' kernel and both Suspend and Hibernate work as expected.
