I forgot to mention that I am running RedHat 6.1 (actually KRUD). so this 
may be different under SuSE.

A friend of mine helped me set up my HP OmniBook 4150 laptop.  What we did was
to create/change the /etc/pcmcia/network.opts file.  I made one for a fixed ip
address and one for DHCP.  See included files.

Give this a try (for the fixed IP one you will need to edit to match your
addresses).
Just rename whatever one your want to "network.opts" and copy to /etc/pcmcia
This may not be an optimal solution but it works.  If any one has a better
solution
I would like to hear about it.

Carl.
