SubjectAPs from the Kernel Summit run Linux

The D-Link DWL-G730AP devices from the Kernel Summit run Linux, And it's
likely a GPL violation, too, since sources are nowhere to be found.

They're based on a Marvell Libertas AP-32 (ARM9) design, similar
to the ASUS WL-530g. A bootlog from the ASUS (which has telnet enabled
for some reason, and thus can be logged in) is at the end of the mail.

A firmware image is available from D-Link ([URL removed]) and it seems
to be composed of compressed blocks padded by zeroes. I haven't verified
yet that it's indeed a compressed kernel, cramfs, etc, but it seems
quite likely.

Anyone interested in dissecting it, and pushing D-Link/Marvell to release
the kernel sources? I'd love to get more out of this cute device ...

PS. I already tried to send this mail twice, but something ate it. I've
removed the URLs this time, hopefully that was the reason the spam
filter at LKML didn't like it.
