I can confirm this.
The FreeBSD ndis layer doesn't support the whole set of ndis features
and is slippery when wet.
Damien Bergamini wrote an OpenBSD driver for the 3945ABG chipset and he
ported it to FreeBSD at some point. It works on fbsd 6.2 i386 only.
Damien stopped developing the FreeBSD version for some reason so it may
be a bit outdated but it works for many people.
You should be able to find the sources for the driver by googling a bit.

Good luck!
