Network is up!

Ok, it turned out that my assembler code was wrong for the external chip selects.
(why do we have at&T and Intel mnemonics with the args in different orders?)
Anyway, I fixed the code and now the external devices work.
I have 2 serial ports + network.
Switched over to using a busybox initrd so that I can fit more in.
Can't get the sound card to work yet, but at least the network is up :)
