Hi,

The following patch adds brightness setting support to the driver and 
cleans up the code a bit. It builds on the work of  Hiroshi Miura and 
takes into account the comments of Len Brown and John Belmonte. The 
patch is against 2.6.8.1-mm1 (though the only thing that might differ 
between -mm1 and vanilla is the Makefile).

I've tested this on my Panasonic CF-R1, and it works beautifully.

As far as I am concerned, besides code cleanups (and possibly figuring 
out the monitor switch thing) this driver is complete.

I hope I haven't stepped on any toes here.
