Hi Paul,

I made myself some more familiar with the Raspberry Pi and prepared the
code for inclusion in LCDproc. Work is done, but I still need to do the
tests (I borrowed a Pi model B for that).

In the meantime you may receive notice that the revision detection fails
on recent models (my revision is 'f'). The line that reads in the
revision number should read hex vales ('x' modifier) not integers.

I will test and prepare a patch today evening (GMT+1).

Stay tuned.
