Here's the PR you were speaking of. 
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/39928
some details in there that might be relevant.  

I was just helping somebody on IRC tonight with getting some DWL-650's
working with m0n0wall.  Out of three, only one would work in hostap. 
Any of them would work in infrastructure or adhoc.  The one that
worked in hostap was identified as:
/kernel: wi0: Intersil Firmware: Primary 0.03.00, Station 1.03.04

The two that didn't work were:

/kernel: wi0: Intersil Firmware: Primary 0.03.00, Station 0.08.02

I just did quite a bit of googling and came to the determination that
anything other than the rev A1-J3 doesn't work with anything but
Windows without some hacking at a minimum, if they work at all.  I
just modified this page to reflect that.

From DLink's support site:  "There are multiple revisions of the
DWL-650, each with version specific drivers, firmware, installation
guides, and other resources."

/me curses DLink for changing chipsets without changing model numbers
