Hi,

nice - I wondered how long it will take until one comes up with such a
thing. With 4 months delivery time I will have to wait some more time
until I get one :(

And I am surprised that LCDproc (at least the non hardware related
parts) work without any patches - great!

Please base patches against CVS HEAD (or a nightly build). Thank you.

Regards,
Markus
