Get the latest copies of the files in src/sys/compat/ndis and
src/sys/dev/if_ndis from the RELENG_6 branch. Note: you do _NOT_ have
to update your entire system, just the files in these directories.
The quickest way to do this is probably with anoncvs:

% setenv CVSROOT anoncvs at anoncvs1.FreeBSD.org:/home/ncvs
% cvs checkout -rRELENG_6 src/sys/compat/ndis src/sys/dev/if_ndis

You can also use a mirror if you're outside the US. See
for a list.

Copy the files to src/sys/compat/ndis and src/sys/dev/if_ndis,
then rebuild ndis.ko and if_ndis.ko:

# cd /sys/modules/ndis
# make; make install
# cd /sus/modules/if_ndis
# make; make install

It should work then. I've been using the same driver on my dual Opteron
amd64 box at home for the past week and it's been very stable
(in SMP mode even):

Nov  9 18:16:59 opteron kernel: ndis0: <Broadcom 802.11g Network Adapter> mem 0xe0210000-0xe0211fff irq 31 at device 1.0 on pci3
Nov  9 18:16:59 opteron kernel: ndis0: NDIS API version: 5.1
Nov  9 18:16:59 opteron kernel: fpudna in kernel mode!
Nov  9 18:17:01 opteron kernel: ndis0: Ethernet address: 00:30:bd:f5:ea:26

[/var/log]:opteron.moo.com{41}% uname -srm
FreeBSD 6.0-RELEASE amd64
[/var/log]:opteron.moo.com{42}% uptime
11:20AM  up 6 days, 17:06, 14 users, load averages: 1.81, 1.52, 1.43

Note that the "fpudna in kernel mode!" message will still show up even
after you fix ndis.ko and if_ndis.ko, but the interface will work anyway.
The messages appear to be harmless for now.
