I don't get any error, i'd like to know what makes me privileged enough
to be able to call s2ram/pm-suspend through gpm while i can't do it from
a terminal.

OK, so all these gconf keys are dead.

Unfortunately, ondemand/conservative is not available on linux/ppc, so
this is a regression for me, this means that i have to get back to
cpufreqd/powernowd.

Anyway, are ondemand/conservative aware of battery/AC ? Or do you think
that powersave/sticking to the lowest freq is useless ?

Thanks.
