This is another call for testing of the wireless changes, if you want to
see 802.11n support in for the FreeBSD 7.* lifetime then please test.

The patch has been updated with iwi(4) fixes and can be found here
To apply it do something like
 cd /usr/src
 gzcat sam_wifi-20070610.patch.gz | patch -p0

This is a diff to a fresh HEAD so if you tested the previous patch then
please revert it first.
