add a driver for the Indy's front panel buttons.
- power button presses are reported to sysmon - volume control buttons are reported to PMF TODO: add better key repeat code. The hardware keeps firing interrupts at us whenever a button is down and not on - say - status change. If we don't clear the interrupt we'll be fired on until someone clears it. We should probably disable the entire interrupt and occasionally poll for button release.
