My DWL-520+ PCI works with the FreeBSD 5.2 acx100 module as reported.  I know this is
probably duplicating some work somewhere, but oh well, I am in the process of lining
up some of the functions.

The file bin2h.c converts all the windows chipset code for acx100
to 4 files (corresponding to the uppercase names) each containing an array
of 32-bit integers stored as hexidecimals (const u_int32_t
(includename)_code [] { 0xea001f9c,0xeafffffe,0xeafffffe,0xeafffffe, .. }

http://sthigpen.freeshell.org/netbsd/acx/radio11.h
http://sthigpen.freeshell.org/netbsd/acx/radio15.h
http://sthigpen.freeshell.org/netbsd/acx/wlangen.h

This windows code is from:

ftp://ftp.dlink.co.uk/wireless/dwl-g650+/dwl-g650+_drv_v1.0.zip
ftp://ftp.dlink.co.uk/wireless/dwl-650+/dwl-650+_drv_v3.06_1007_inc_utility.zip

and this does work with the PCI DWL-520+.

as per the discussion earlier, the Intel Prism code does provide some
form of template:
