After loading everry kernel module that looked possibly relevant:

d146(7.0-C)[12] kldstat

d146(7.0-C)[13] 

and issuing the same commands the script did (by hand) and verifying
exit code 0 from each, and still seeing "no carrier":

d146(7.0-C)[13] ifconfig wi0

d146(7.0-C)[14] 

I plugged in the PCcard ed(4) device [note -- not "de(4)," as I
previously reported) and re-ran the script:

d146(7.0-C)[14] sudo sh /usr/local/etc/rc.d/nic_init faststart

Huh?  Why would poking at ed1 change anything in wi0??!?

I tried pulling the ed1 devvice out (afterward) and running the script
again, but the result is still (or is that "again?") "no carrier."

I tried the xl0 and ed1 devices, they appear to work without anything
special, as expected.
