Sorry - I use GtkTerm normally, but clipboard support doesn't seem to be

Kernel command line appears fine, see below:

<snip>
=> run nfsargs
=> printenv bootargs 
bootargs=root=/dev/nfs rw
nfsroot=192.168.0.254:/home/timc/opt/eldk-4.2/ppc_4xx

bootargs=root=/dev/nfs rw

I'll push on with 2.6.32 and see if I can simply sidestep the eth0
weirdness :) Of course, if you have any ideas, they would be welcome!

Thanks again,
