AFAIK, true in both counts.. I use 1.7.4 firmware with wpa_supplicant on
Linux and I have seen some discussion about 1.8.4 and it having some
problems. Lower version like 1.[3,4].x did not work either.

Hmmm, but I think that it does not depend on FW-level as I have already a
working solution == FW 1.74 and wpa_supplicant 0.4.8 on linux platform. 
Now the "man wpa_supplicant" in NetBSD refers to following drivers: ath(4),
ipw(4), iwi(4), ral(4), wi(4) and I think this is somewhat misleading as I,
at least, expected wi-driver to work with wpa_supplicant and being able to
do more than just a simple WEP-based connection.
I guess you are right saying that wi-driver needs some modification...
