So I built a keymap file that closely approximates the scancodes
on the Jornada 720 and I can mostly type in an xterm...

I have some questions though...

after a few characters, or at some random time, and most specifically 
after I press a ctrl-key, the control modifiers seems to stick. ie:
every character after that is sent as a control character.  'xev' 
reports that press/release events are indeed received when I press 
the 'control' key but the release never seems to make it into the 
server or is ignored.  Any ideas?

How to deal with the touch-screen.  How is this normally done? It
looks like tapping on the screen with a pen gets both a mouse warp
and button press/release.  Is there just no way to get any other
sort of behavior so mark/past works in an xterm, or twm menus can
come up, or ??  I guess this is just a basic limitation of the 
technology.

I must say, it _is_ pretty neat.
