thanks very muchly. i hope in future to contribute on the community side -
though my focus will be working on OE, not OM and thus i'll be building with/on
FSO. working on ASU (2008.08/09) means i will always need to maintain a fork
and battle with whatever om's design team decides is to be for om, so it's
easier to work with FSO as i want to focus on the community - i.e. us -
nerds. the actual userbase of the freerunner. :)

there's 2 issues here. 1. yes sometimes it doesnt wake up at all - ever.
sometimes it never sleeps! qpe holds the apm suspend process up (probably due
to gsm modem issues in trying to set the modem to standby mode). so you can
plug in with usb and ssh in and its alive - but screen stays unlit as the
suspend process is hung. so you will ant to check which is which. i do say -
since i removed my sim card... suspend/resume is much more reliable! :)

yeah. this is because e/illume uses x's screenblanking infra. the problem here
is - you can't stop x from turning on backlight on a touch. i may need to
change this to bypass x and talk to backlight directly - it's really ugly and
makes things much less portable with the same codebase from device to device -
but may just be a necessary evil.

btw- i've improved things a lot - asu.dev has the latest updates. :)
