As ajax mentioned, the preferred solution is hopefully going to be the
evdev driver.

I should note that at the moment the support is exceedingly minimal, and
that some time here we need to figure out a better way to indicate the
various tools.

(I am oh so _not_ convinced of the insanity used by the other drivers
that support multiple tools, but I will admit that the applications
currently expect that behavior.  And the current method of using the raw
button numbers gives us button numbers up past 64, so it's probably not
a solution either.)

Thanks to Alex Deucher I should have a tablet by the end of the week,
not supporting all the odd whiz-bang tools, but enough that I should be
able to get the driver a whole lot closer to where it needs to be.

Oh, and you'll want to look at the CVS version of the driver, I need to
do a release once I've made sure that there are no more surprises.

I'm not a cat person, but I can just imagine the reaction of your
average feline to someone's attempt to stuff it into a pair of
pajamas.

Now picture your hard disk after the thing installs.
