I'm still looking for a solution, and as it seems that nobody knows
what's going on, I'm trying to debug that situation by myself. To do
so, I added debug messages (using logger) at various places. I'm actually
not at all successful in finding out what's going on :(

Right now I'm wondering, what's supposed to happen, when the
"Hibernate" button is pressed on the Gnome Logout dialog, when
that dialog is shown after the Log Out button is pressed.

What happens is, that the Log Out dialog is shown. There, I'd like
to hibernate the system by pressing the Hibernate button. But when
I do so, just nothing useful happens. The WLAN goes away for a short
time, and that's it.

Somewhere, I read, that /usr/sbin/pmi should be executed? Well,
that doesn't happen here. To /usr/sbin/pmi, I added at the beginning
of the file, after #! /bin/bash:

logger -t pmi "In $0 - pmi"
logger -t pmi "command = $1"
logger -t pmi "event = $2"

When I run pmi manually, those 3 entries show up in the syslog. But
they do NOT show up, when I push the Hibernate button.

I'd really like to know, what's supposed to happen, when the Hibernate
button is pressed and how I can configure this. I'd also be interested
to know, to what package this log out dialog belongs. On Gentoo it
looks *VERY* different than on Ubuntu. How comes?
