How about this for defaults:

- heartbeat for led3
- cpu0 for led4
- cpu1 for led5
Good idea. Will try.

What I don't exactly know is if these gpios based on an I2C-expander
can handle cpu activity triggers or if they are locked up if this i2c
processing triggers another cpu activity...
Oh right, if the GPIOs are on the i2c bus it's probably not a good
idea :) Or at least will be inaccurate if the bus can sleep.
