Ok... It's been a while but I remember now. It's not a out-of-tree
kernel pain, but an out-of-tree X pain. If somebody hasn't ported
evtouch to the latest greatest X then somebody will have to port the
code.
I haven't looked to see if the evtouch project has recently updated with
the newer ever-evolving X code.
BTW: I've always wondered why the evtouch people didn't push their code
into X

Ok... just tried packaging evtouch and end up hitting compile errors for
a couple of things that no longer exist in the new X, specifically:
<snip>
evtouch.c:33:25: error: xf86Version.h: No such file or directory
evtouch.c:34:49: error: missing binary operator before token "("
evtouch.c:77:25: error: xf86OSmouse.h: No such file or directory
evtouch.c:142: error: 'XF86_VERSION_CURRENT' undeclared here (not in a
function)
</snip>
The code needs to be ported. I have no idea if the evtouch project is
already working on this, but I didn't find a source repository with code
that builds on the tip of X.

I've always seen the evdev X driver but never know how to use it.
Is the associated kernel driver something that is in our source
(2.6.29-rcSOMETHING) and just not configured in the build, an
outstanding patch, or an out of tree driver?
