Sure, the kernel i currently using is available here:
http://www.hick.org/~johnycsh/code/mach_kernel.dev
Note that youl mstill need the tarball from before to
change the mac. Also, dont forget this patch -cant- do
lowlevel 802.11 association/authentication stuff. I'm currently
trying to figure out the best way to do that. Im secretly hoping
that mick will take an interest and lend a hand since he is undoubtedly
the more experienced kernel hacker.
