hmm, afaik qtmoko already uses rtc to wake up from suspend (so you have at least 20mA suspend current) but I have to check. 
So I think most logic is already there. Setting the rtc alarm for suspend or for power on is the same. the -m option just tells rtcwake
what to do afterwards and -m off is simply an ordinary shutdown. twl4030 is
configured by default to power on on rtc events. Keyword in the source:
But what happens might be that e.g. qtmoko clears the rtc alarm setting
on shutdown. At least it can save alarm settings
in its settings file, so it has only to do the right thing after

so, several things to check...
