[driverloader] Now for the real problems...

ifcfg-wlan0 is just a place holder that never gets started -- it is a
backup of how I think the wireless should be configured. There is also
an ifcfg-eth1 which matched the alias in modules.conf (given below)

alias eth0 via-rhine
probeall usb-interface usb-uhci
probeall scsi_hostadapter ide-scsi
above snd-via82xx snd-pcm-oss
alias sound-slot-0 snd-via82xx
alias eth1 driverloader

When I want to test the wireless, I do an 'ifup eth1' so I really think
it is safe to leave ifcfg-wlan0 alone.

ifcfg-eth1 has its WEP turned off and I have turned off WEP on the AP.
I removed the FREQ and CHANNEL settings in the ifcfg-eth1. No changes
when attempting to use wireless.

Lastly, all works well from XP. In XP, I hit Fn-F2 and a little light
comes on indicating that the RF is active. When I press Fn-F2 in Linux,
the same light goes and the kernel CPU usage soars to 70-100%. So,
something is happening. Just not the right something.

What I really need is an RF spectrum analyzer to see if the card is
really becoming active and at what frequency.
