Yes - I've started with extracting the PDA information in a way so that it
can be read by the likes of prism2dl. I find that I now need to decode the
hex files in much more detail (Up to know I assumed it was just an intel
hex file which needed to be uploaded in a some bit of ram. Turns out there
is more to it than that :-(.

Aye - I've also added an ioctl to get the 3 id/major/minor/variant values
for nic/pri/sec; which is enough to drive prism2dl together with the PDA
info.

Thanks - will limit myself to that.
