If you are using the cgminer I linked in this thread - know that it will only run on a Zipit Z2 device (more specifically, one that is running the default and very outdated kernel).

I had to build it in scratchbox, in a static mode (all of the libraries are bundled into one fat stupid binary).

So yeah - it's worthless to any other device.  But hey - you should work on compiling it from source on your iPAQ.  Because, why not?  If nothing else, as a goof (ref: http://www.youtube.com/watch?v=xtcbVUNO1NY).
