We gave that patch a quick try today and it doesn't seem to work. We
don't get any events from the touch screen anymore. We need to debug
this further, hopefully by the end of this week.

If there's anything obvious in the setup of the threaded IRQ handler,
please let us know. Otherwise, I'll get back once I have a fixed version
of the patch.


Thanks,
Daniel
