Apps should definitely not program the timer themselves.
They should call into linux instead, for example by sleeping until the 
desired point in time.

Linux already support hundreds of sleeping apps using only one timer on 
a pc. The timer is simply set to expire at the first upcoming event.
I don't know if the freerunner kernel uses a timer capable of
waking the phone from suspend when managing sleeping processes - but it 
could be made to do so.
