I would assume you are doing this with NM. You could either change it to
register the interface (this is not from -D option, but from the D-Bus
message) with the nl80211 driver or try to build wpa_supplicant without
WEXT support (which would make the nl80211 wrapper the default one). I
don't think either of these are yet acceptable as a generic solution,
but making NM request driver "nl80211,wext" could be a suitable first
step when moving to wpa_supplicant 0.7.x (this makes wpa_supplicant
first try with nl80211 and if needed, fall back to WEXT).

There still one remaining WEXT operation even with driver_nl80211.c in
wpa_supplicant, so we are not yet there, but there is work going on in
getting that added to nl80211 after which point -Dnl80211 (or
-Dnl80211,wext for more likely distro use) should allow this goal to be
met.
