New Dell laptop dificulties

I have a new Dell Inspiron 1100. The first thing I did was wipe the
harddrive so I could start with a clean slate. Due to work
considerations I have to use windows XP for certain things, so I now
have a dual boot with XP and Redhat 9.0.

On the linux side I am having a few networking problems. The box came
with a broadcom 440X nic, which is unsupported by Redhat out of the box
and I also use a Linksys WPC11 wireless card, which is supported by
Redhat out of the box.

I downloaded and installed the drivers for the broadcom installed then
and that works fine. I also configured the wireless card and it works
fine, except that I can't get it to work in encrypted mode yet(probably
my typing of the key).

With the wireless card in place, it is ETH0 and the broadcom is ETH1.
The problem arises when I boot into Linux when the wireless card is not
inserted, which is the case when I am at a remote site. Then the
broadcom is recognized as ETH0 and it tries to use the orinoco prism
driver from the wireless card. And I then have no connectivity at all.

What I want to happen is, I think, to have the broadcom designated as
ETH0 using the driver I install, but not have ETH0 activated at boot and
have the wireless designated as ETH1 and activated at boot when it is
present.

Any ideas how to accomplish this?
