Comment(by raster):
ok here's my summary.
remove sim card and suspend/resume gets a LOT more reliable. what i have
observed a few times - on suspend ompower executes apm -s - but this never
returns. qpe holds suspend from happening indefinitely via its apmbios
hooks. remove sim card and qpe no longer does this. this solves the
"system is up but screen is blank" problem - ompower is stuck waiting for
apm -s to return - which it doesn't, so it never turns backlight on again
(as that code is right after apm -s ends).
there is a general kernel wakeup issue. here's my log on how many repeated
suspend/resumes u need until it kicks in:

(24 suspends till it happend) - but at this stage the device is dead -
nothing wakes it up. it stays suspended (or off - i don't really know)
until i rip out and put the battery back in.
so as i see it we have 2 issues here:
1. qpe (holding up suspend - i suspect due to calypso not wanting to power
down nicely).
2. kernel literally being dead to the world on wakeup or hardware being
dead.
so first - try lots of suspend/resume tests without a sim card in. is it
"more stable". do you ever get the system resumed (just check if a
cdc_ethernet device was "plugged in" on your pc as i got above from logs).
if one is registered but the screen is off - try ssh in. check the process
list - is "apm -s" running?. if so, kill it and backlight should pop on.
without a sim card in i have yet to see this happen. with one in this
happens.
other than that - if you attempt to resume (power button is my manual
testing) and it doesnt come on at all (no cdc_ethernet device advertised)
something has gone bust below or in the kernel.
