s2ram doesn't work. s2ram --force also doesn't work. It's not a
permission problem. The error is "machine not found".

However, the laptop happily suspends either with the hotkey, or when
invoked from gnome (ie by power settings, or from system->shutdown and
then choosing suspend).

I have the same situation on a sid desktop. It suspends great via gnome,
but once again, not via s2ram (it never suspended when I was using
Ubuntu 8.04, so I am delighted about this).

I have tried hard but I've never understood how gnome does suspend.
If I could work that out, could I configure gdm to call an alternate
script?

When I look at /usr/share/pm-utils/defaults
I see that everything is commented out; the comments in file indicate
that this means the kernel is managing suspend.
