a quick look seems to indicate that a bunch of the necessary command
definitions are present in smu.h already. Search for SMU_POWER_EVENTS
and below.

You probably need to send a SMU_CMD_POWER_EVENTS_COMMAND with
SET_POWERUP_EVENTS and SMU_PWR_WAKEUP_AC_INSERT as arguments.

You can find examples of how to send SMU commands there:

Fell free to submit your resulting new utility to powerpc-utils :-)
