yes calling apm -s gives device or resource busy and pressing pwr button
turns the screen off but not suspending, but u have ssh still active and
everything still on, only screen off,  so both ways disabling gsm via call
to sysfs is disabling us from suspend

yes that's what i believe but problem is i don't know how the distribution
goes to do the suspend exactly, any references to how suspend is being
called in om2008.9 ?

does the same occur in debian arne?
