[driverloader] Switch back and forth between interfaces?

Quick question which I just stumbled onto and recalled wondering about in
the past.

Take this scenario:

Laptop boots with eth1 enabled which grabs IP from DHCP - this device is
driverloader (2100b card), eth0 is set to not start on boot. Box comes up
and all is well, I can get out to the net no problem. I fire up Fedora's
(FC2 BTW) network applet and deactivate eth1 (driverloader) and activate
eth0 (local onboard nic). Now, I can work with eth0 no problem as well and
get out to the network. Now, deactivate eth0 and attempt to reactivate eth1,
and eth1 can not get an IP from the DHCP server nor associate with the
access point. Happens every time... Not sure why but this has followed me
from FC1 to FC2 when using the driverloader software. 

Note that all is fine if I use ipw2100 but I prefer to use driverloader
since for whatever reason javahmo (tivo soft) won't work with the ipw2100
driver (java barfs with network errors for some reason).

Anyway, hope I made some sense and others could maybe shed light.
