Thanks a lot, Stef!

Darkness is the essential reason I don't use my 210 with Sane right now, 
so it's great to know the situation has improved, and I would love to 
see how much it has.

I see your changes are in the git repo, but is there a package available 
somewhere? I've found 
<https://launchpad.net/~rolfbensch/+archive/sane-git>, but even though 
it packages daily snapshots, it is not daily itself, and it currently 
doesn't contain your changes.
