I installed compat-wireless against my 2.6.30.1 kernel,
and also the iw command.

I've read some docs, however I'm not sure what the next step should be. 

My general idea is that I should be able to see a list of
access points, however iwlist doesn't tell me anything new.

# iwlist wlan0 ap

wlan0     Interface doesn't have a list of Peers/Access-Points


I'm appending some diagnostics.

Here's what dmesg tells me after 'modprobe ath5k'
