* Driver marv88w8363 now links. Can't test it as I don't own this hardware.

* Firmware is needed:
  a) Download the firmware files from FreeBSD 8
     here http://svn.freebsd.org/viewvc/base/release/8.0.0/sys/contrib/dev/mwl/mw88W8363.fw.uu?view=log
     and here http://svn.freebsd.org/viewvc/base/release/8.0.0/sys/contrib/dev/mwl/mwlboot.fw.uu?view=log
  b) Use the tool uudecode <firmware-file> to convert both files into their
     binary format.
  c) Copy both files to /system/data/firmware/marv88w8363/
  d) Rename first file to mw88W8363fw and the second to mwlboot
  e) Copy the License from http://svn.freebsd.org/viewvc/base/head/sys/contrib/dev/mwl/LICENSE?view=markup&pathrev=193240
     into this directory, too.
