Network In Single User Mode

[Michael Stearne]

I have a Macbook Pro that I just was attempting to update to 10.4.9
and the update kernel paniced and I haven't been able to boot
successfully since.  I was thinking about rerunning the update from
the single user mode startup using

sh /etc/rc to get OS X running in Single User Mode and then
softwareupdate -i -a to do the update.  I can't seem to get the
machine on the network though.  ifconfig only shows the 127.0.0.1
interface.

Any ideas on how to get this machine back up with reinstalling the OS.
 Safe Boot doesn't work either.

Thanks,
Michael
