Almost.  Most of the direct WEXT scanning code is already gone, and
replace by queries to wpa_supplicant.

What I'm talking about here is the special handling code for cards that
don't support wireless scanning at all.  It was initially written
specifically for the Orinoco driver, which didn't support scanning until
2.6.13 or something.  The code works around the fact that Orinoco didn't
support scanning by copying the entire "allowed" list of access points
to the scan list, and by not autoconnecting to any access point, but
waiting for the user to request a connection, and not requesting or
converting scan results.
