Having taken the lid off, the board inside has a bunch of resistors and
two 74HC125D drivers, which means it's either Wiggler-compatible or else
has a slightly different pinout. Getting this to work with libjtag is
probably straightforward; I need to trace out the lines and find out
what goes where. Will report back if I get a reply.

Incidentally, re getting a copy of the PBM firmware; having thought
about it, it's probably best if I do it myself. It's not particularly
difficult and it's probably best to remain as squeaky-clean as possible.
