You wrote the driver? I just used the existing one in the 2.6.28.2 kernel.

I seem to recall you need disable the interrupt upon #PENIRQ and allow the
polling code to do the job of determining the pen up event.

The existing driver uses the event system. The easiest way to see what I did
is to unpack a 2.6.28.2 linux tarball and apply the patch I've attached to this post.
