I just looked at pm-suspend's source. This error message means that
in /sys/power/state there's no mem present (try 'cat /sys/power/state'
to see what is supported).

This one can cause problems at resume, but not at suspend time :-)

Is this a desktop (Pentium M was for mobile AFAIK), isn't it?
Has this machine ever been able to suspend to RAM?
If so, have you changed something in your BIOS?
Please check what these two say:
grep -i 'power states' /var/log/messages
grep -i 'suspend' /var/log/messages
I've seen something like / long ago :-) /:
'Software Suspend has malfunctioning SMP support. Disabled :('
but have no idea what the current status is...
