Glenn,
I don't think there is any difference between the later revision 1 and
the revision 2 boards other than differences in the GPIO bus.
I think I am right in saying the later revision 1 Model Bs had 512 MB
rather than the earlier 256, but I might be wrong. I don't play close
attention to the Broadcom hardware notes.
The revision 2 boards started to be sold in early September last year so
if you got yours well after that, chances are it's a revision 2 board.
