Oh boy. There goes another month of my PhD :)

The problem with the PXC200 (apart from imagenation's wonderful policy
regarding documentation, which is really not warranted given the board's
quality - sorry guys, if I unplug a camera, I don't regard my system
freezing as acceptable) is that there are at least two different models
out there (as in different on-board hardware) but with the same model
number. Alessandro's driver was able to handle this (I think), but when
I put his code into bttv, it was a quick cut'n'paste job so it only
initialises my model of the board properly.

It works for me - again, different hardware on the boards.
(And I do get the same values read back as well)
