Actually, I won't for now, because there's some progress. :-)

Namely, on a non-preemptible 2.6.18-rc5-mm1 the only module that causes
problems is snd_hda_intel.  Unfortunately I can't unload it before suspend,
because the kernel oopses on every attempt to do so, but I'll report this
in a separate thread.

I'll experiment with the preemptible kernel when the snd_hda_intel issue gets
resolved.

Greetings,
Rafael
