It was a lot harder than I expected, and that was following the step-by-step 
instructions at http://linuxwacom.sourceforge.net. It probably doesn't help 
that I'm using a 2.6 kernel, but I thought it would be reasonably straight 
forward. It was some combination of kernel update, modules vs. builtin, and 
updated hotplug scripts that did the trick in the end.

Yes, it has tilt. Haven't played around with it much yet but Painter uses it 
so that you can point the airbrush in different directions, producing 
ellipses or circles. I had wondered what tilt was used for until I saw that. 
Very nice.

I've managed to get it to work in krita now but something odd is going on as 
it's impossible to draw straight lines (with the brush tool). They're always 
rough and jagged, as though my hand was shaking badly. The strange thing is 
that even if I put a ruler on the pad and draw along the edge of that, it's 
still rough and jagged. Haven't investigated why yet, but it works fine in 
the gimp.
