b43: Add support for new firmware

ソースを参照 
This patch adds support for new firmware.
Old firmware is still supported until July 2008.

To get new firmware, go to
ftp://ftp.linksys.com/opensourcecode/wrt150nv11/1.51.3/
and download the tarball. We don't have a smaller tarball, yet.
That will be fixed later.
You can extract firmware out of the "wl_ap.o" file contained
in this tarball using latest fwcutter. You must pass the option
--unsupported to fwcutter.
Fwcutter-010 with official support for a new firmware image will
be released soon.
