Thinkpad T20 wireless troubles

[Chris Brotherton <chris@protonlab.net>]

I just recent got an old T20 and I am attempting to use Debian on it.  I am
using a PCMCIA orinoco wireless card.  Here is the crazy part.  The card is
recognized by the installer.  The installer asks me for my essid and my WEP
key.  After I input the information, the wireless card get its ip address over
dhcp and then works flawlessly.  The trouble comes when I finish the install
and boot the machine.  Once the machine comes up, I cannot get the wireless
card to work.  iwconfig shows that it has all of the correct information, but
it cannot get an ip address.  I have tried both 4.0r1 and a testing snapshot.
Both have the exact same problem.  

Can anyone help?  

Thanks,
Chris
