Yea, i compiled it in on the next run through, and it resolved this
error.  What i don't understand is that I don't normally compile any
support for it in the other 2.4.x kernels i've built, and never saw this
error before.

Nope.  I've not bound 127.0.0.1 to anything other than lo.  This error
also disapeared once i compiled af_packet support into the kernel.

Its identical under both the 'good RH' and 'bad 2.4.18' kernel:

Socket 0: CardBus hotplug device
Socket 1: empty

Yea, it seems this way.  I'm wondering if this is something new for
2.4.18, because on my SONY VAIO that also has a PCMCIA NIC (not a Xircom
though), i haven't compiled any af_packet support into the 2.4.17 kernel
it uses, and everything works just fine.

Hrmmm...it appears that I am missing a few under 2.4.18, namely:
yenta_socket
pcmcia_core

However, i'm fairly certain that I compiled them into the kernel, rather
than making them modular.  Actually, if I restart the network service,
eth0 comes up, and i can ping out.  So, i'm guessing I need to add an
alias entry into modules.conf for xircom_cb so that it will get loaded
on bootup.  So, i guess the only remaining mystery here is why does eth0
come up on its own when booting into the RH kernel, but not mine?

Thanks for you help, David, i appreciate it.
