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).


$ cat /sys/power/state
standby disk

On my machine the above command returns:
mem disk

So mem is indeed not present on your machine.

And is it a configuration problem or hardware inability?

The last thing you can try is try to reconfigure your BIOS. There
are some settings (I have no desktop currently) that enable/disable
S1/S2/S3 states and change ACPI/???'s version. Disable legacy USB
support (be sure to have PS2 keyboard just in case) and... try...
A friend of mine got his PC suspending to RAM after changing
something in the BIOS, but I never asked what exactly. Luck.
