Hello Chris, hello everybody else,
I am new here. Thanks to your work, Chris and your sources ( 
http://sites.google.com/site/bez625/updates-1/update120410 ) I can use 
an Optibook 3600 under Sane for scanning in some pics for my lectures. 
You can find my current diffs in 
cb-pobook-initial.diff is how I transposed Chris' work to Sane git 
3de5c8738 (Mon Nov 8 18:01:29 2010 +0100). shifted-shading.diff contains 
my own work, a rather strange shading function in which the color matrix 
is rotated every 256 values. I found that by writing less than 3 color 
channels. In the same directory you can find some test scans at 
different dpi. The 600dpi one is a bit marginal as we do not yet use 
offset and gain calibration. 1200dpi scans do not work yet.
For everybody who is willing to test the backend I have also put the 
Ubuntu packages up which I use.
