I had a similar problem, and I ended up configuring the network
card as eth2, and driverloader as eth1 (I think - if you want
details I'll get them later - you can send me email off the
list).  Then I could use the network and driverloader and go back
and forth from one to the other with no problem.  The trick for
me was to make sure that the definitions in /etc/modprobe.conf,
/etc/sysconfig/hwconf, and /etc/sysconfif/network-scripts all
agreed with each other about which device was which, and which
was associated with which driver.  (The drivers were in
modprob.conf.)  I had to do a lot of this by hand rather than
relying on system-config-network.
