linux-wlan on OS X

[Richard Sperling]

Small problem. Ubuntu Linux PPC doesn't support the Airport Extreme 
wireless card on my Apple Powerbook G4. So I've got no Internet access 
at the moment. I have another USB wireless card, but it needs the 
linux-wlan driver to make it work. I need configured kernel source, 
however, in order to compile linux-wlan. So my question is how I can 
manually download and install the kernel source? Running uname -r 
yields 2.6.8.1-3. I know there's  a kernel security update available, 
but I'd like to get linux-wlan working first. Once that's done, then I 
can use apt-get to grab the updates. Any help is appreciated.
