I posted a patch for review on the openmoko kernel mailinglist. Basicly due the
LED connection you can not set any pin individually on the GPIO Bank the LEDs
are connected to. This is because on write the current state is read, the bit to
change masked out, ored into. On reading the LED state is 'lost'/0.

So every write access to the GPIO bank B needs to add the LED state before
writing out the value. Otherwise your LEDs would go off when you start the
vibrator or turn on the modem.
