laptop dhcp fails on severn

I'm  running a laptop with 2 pcmcia network cards on severn. One card ( A ) 
is connected to a cable modem - optimum online - the other ( B ) to the lan. 
ool uses dhcp, so A is set to uses dhcp. All worked great, until severn.

dhcp no longer works.  I've switched the cards. Both work on the lan with 
static ip addresses. I've flushed iptables. I even brought in another 
laptop. Same result. But...if I connect ool directly to a severn 
workstation, it works fine.  So it's only laptops.

Something's screwed up. Don't think  it's dhclient or dhcpd - tried both.  
Here's a snippet from ethereal of traffic over the card. It's sending out 
discovers and getting back offers. But it doesn't seem to see them. Is 
dhclient responsible for seeing them? Since the workstation had the same 
dhclient rpm, I assume it's a network script problem related to pcmcia.

Does anyone have a pcmcia network card that works with dhcp under severn?

I sure don't.

thanks for any help
