Default BCM4331 and ndisgen

Hello everybody, how are you doing,

I am trying to get my laptops internal Broadcom BCM4331 wireless working.
It looks to me like the Broadcom drivers in FreeBSD don't support networking for this one, so I am trying to get it up with ndis. (I found an old stackexchange question were somebody said they got a 4331 working on FreeBSD with ndis, but sadly they didn't say how)
I extracted a BroadcomWirelessWin7x64.exe file, which contains a driver, which I know works with Windows.

It contains these files:
bcm43xx64.cat    bcmihvui64.dll  bcmwl6.inf      bcmwlcoi.dll
bcmihvsrv64.dll  bcmihvui.dll    bcmwl6.sys      DPInst.exe
bcmihvsrv.dll    bcmwl664.sys    bcmwlcoi64.dll  DPInst.xml
ndisgen bcmwl6.inf bcmwl6.sys
resulted in

ndiscvt: line 3095: VID_02d0&PID_4319&FN_1\LocationPaths\*: syntax error.
this is the line in question:

For now i just deleted that, and with that ndisgen generates a bcmwl6_sys.ko file.
(It asks if I want to include additional firmware. Do you think any of the files listed above could contain that?)

I added bcmwl6_sys_load="YES" to /boot/loader.conf.

Now if I do ifconfig there still is no bwn0 (same as before) or a ndis0 device listed.
What am I missing?
kldstat lists the bcmwl6_sys.ko file, so it is loaded, right?
On the dmesg the 4331 is still listed as bwn_pci0: . Does this mean it is attached with the bwn driver, and therefore unavailable for ndis. How would I remedy that?

How about a hardware solution?

I had a Broadcom wireless chip in my laptop but I replaced it with a Ralink chip...

Check out the lyrics to the OpenBSD 3.7 release: 3.7 The Wizard of OS
When you see a good move, look for a better one.

Know than the other approach that some other users of the BSDs and other Unix like operating systems have also opted to replace their computer stock broad com chip set based WiFi cards with either Intel chip-set biased WFI adapters.
