Right now, there are only a few examples in the form of drivers in
various programs:

- the original blinkenlights
  http://projects.qi-hardware.com/index.php/p/ben-blinkenlights/source/tree/master/bbl/bbl.c

- atben (needs some cleanup)
  http://projects.qi-hardware.com/index.php/p/ben-wpan/source/tree/master/tools/lib/atben.c
  
- avrdude
  http://projects.qi-hardware.com/index.php/p/ben-blinkenlights/source/tree/master/uart/avrdude/patches
  
- f32x (various files)
  http://projects.qi-hardware.com/index.php/p/f32xbase/source/tree/master/f32x/
  
avrdude is used by:

- uart
  http://projects.qi-hardware.com/index.php/p/ben-blinkenlights/source/tree/master/uart

  UART is designed to use the Ben's crystal-based block. For this,
  avrdude will need to provide this clock. This isn't implemented yet.
  For an example of how to do it, see atben.c above.

Agreed. Here's an unfinished library that also takes care of unbinding
and re-binding the MMC driver:

(I didn't finish it back then because of a kernel bug in the bind/unbind
logic. Need to revisit this.)
