If the suspend mode (i.e. power-off mode in Samsung terms, i.e. self
refresh SDRAM and wake-up configured) is the mode that will be used as
state 90% of the run-time (most of the time the phone will be waiting
for events in a pocket) couldn't we simply leave the modem running in
run-state and leave the suspend/resume feature as a later enhancement?
Well, your choice of course...
