Unfortunately I think you mean the onboard WLAN. I didn't buy that, because
I heard there are some problems with it under Linux, and I already had a
Cisco Aironet 350 pcmcia card, which I use now in the T30 running RH 8.0.
 I had to compile in the Aironet /proc interface (though none of the old 
Aironet drivers) and the Cisco 350 driver, all of that is available in the 
Redhat 8.0 kernel config (no additional pcmcia or Cisco source necessary).
It works fine for normal LAN connection and also in promiscuous mode
with kismet (I use kismet 2.6.2). I use it intensively in both modes and 
until now had no problems.  I heard the original Cisco driver from their 
Website doesn't allow promiscuous mode, but I didn't verify that.

Why do you need that ?  I use the onboard Intel pro 100 as eth0 (e100 driver
instead of eepro100) and the Cisco 350 as eth1. There are never the same IP-addresses 
on them and therefore no conflicts. And if you want to change the default route for 
some reason, it's only one command while you are up and running.
