Lost network trying to upgrade to testing

["Randy W. Sims" <ml-linux@thepierianspring.org>]

I've been running Woody (with a 2.4 kernel) for a while on my laptop. I 
decided to try out testing, so I followed the steps in the Debian 
Reference. But at the end of section 5.2[1], I was left without a 
network connection: cardmgr was uninstalled, so my LinkSys network card 
is not being setup; ie, /dev/eth0 is gone. How can I complete the 
upgrade without a network connection? I still have my original Woody 
CDs, but I'm unclear how I should proceed.

Thanks,
Randy.
