Right, next couple of problems.

udev isn't creating the ttyO* nodes for whatever reason on my fs - does
anyone know what device major/minor numbers these end up with? It seems
they're dynamically assigned.

There's also something fishy going on with networking (if I configure
PNP IP, I get an IP:

ks8851 spi1.0: message enable is 0
ks8851 spi1.0: eth0: revision 0, MAC 1a:6a:b1:02:1d:90, IRQ 194
IP-Config: Got DHCP answer from 0.0.0.0, my address is 192.168.0.144
IP-Config: Complete:
device=eth0, addr=192.168.0.144, mask=255.255.255.0, gw=192.168.0.1,
host=192.168.0.144, domain=arm.linux.org.uk, nis-domain=(none),
bootserver=0.0.0.0, rootserver=0.0.0.0, rootpath=

but the board doesn't respond to that IP address. Meanwhile the DHCP
server shows:

DHCPDISCOVER from 1a:6a:b1:02:1d:90 via eth0

in its log, and the ethernet address appears to be random for each boot.
Obviously, as I can't log into the board via any means, it's nigh on
impossible to work out what's actually going on.
