Hah. I've just bought a house. Suddenly I don't seem to have any time
any more...

Oo. I didn't know that; I thought PBL was giving me the raw data
directly... hmm. This makes a big difference for the stuff I'm doing;
now I know that I can call PBL routines and get *reliable* data off the
flash. (It also explains why the PBL flash access routines are so

I'm not entirely sure that my E2 *has* an SMC socket. There's certainly
no metal socket soldered to the motherboard; someone suggested that it
might be possible to insert a card and have it make contact with the
metal tabs on the motherboard without needing a socket, but I'm not
convinced of this. I'm still trying to scrounge one up to find it.

How complex would a minimal USB stack be? Could we load data off a USB
storage device?
