bwi(4) does not support your card.

You must create wlanX first.

NDISulator on amd64 is mostly broken. It can panic on driver
initialization (fixed in my git repo).
Also fpudna in kernel mode can cause panic (not yet fixed).

Interesting, that version of driver does not use symbols which cause
crash on driver initialization of older driver...

Of course most 6.X drivers dont have support for older NDIS 5.1 API.
