I'm working on wakeup from suspend.
This would have the benefit that there is no need to
shut down the system.
I'm testing with DVB and VDR and both survive SUSPEND
perfectly (dvb-0.9.4 + vdr-1.0.0pre4).
The live picture contines during SUSPEND.
If every thing works perfectly the system (vdr) would
resume after suspend triggered by eighter RTC alarm or
serial interrupt (RC-control).
This would realy work like a settop box
