I ran 'sh -x /etc/rc.d/wpa_supplicant start ndis0' to see how the script 
was starting the program.  Here is the original command line:

/usr/sbin/wpa_supplicant -s -B -i ndis0 -c /etc/wpa_supplicant.conf -D 
bsd -P /var/run/wpa_supplicant/ndis0.pid

I replaced '-D bsd' with '-D ndis' and still got a return code of 255. 
I double-checked to ensure the module was loaded, and adding '-dd' did 
not increase the debug output.

I also read the /etc/rc.d/wpa_supplicant script to see how it detected 
whether or not to use '-D ndis'.  Turns out it calls a function named 
'is_ndis_interface()' which checks a sysctl named 
'net.wlan.${1#wlan}.%parent' but there is no 'net.wlan.ndis0.%parent', 
nor is there any 'net.wlan.ndis0' keys.  There *is* 'net.ndis.0.%parent' 
which is set to pci1 and 'net.ndis.0.%driver' which is set to ndis -- 
the latter sounds like a possibly sensible test for '-D ndis' if you ask 
me.

Anyway, the fact that the sysctl wasn't present makes me think the 
failure to load /compat/ndis/rate.bin might have caused 'ndis_attach()' 
to not call 'ndis_create_sysctls()', or 'ndis_attach_pci()' to not call 
'ndis_attach()', or so on -- but I can't tell where 'NdisOpenFile()' 
gets called so I'm not sure.

Does this sound reasonable?  What do you think?

Jack.
