I would guess that it's a Wireless Extension problem. I did some
changes for cx3110x in OS2008 and that most probably broke the
backwards compatiblity with wlancond from OS2007.

Wireless Extensions is a bit of a challenge, to put it mildly. The
worst Linux kernel interface I have seen :/

Fortunately Lauro Venancio posted a patch for supporting
wpa_supplicant to cx3110x-devel. I haven't yet tested them myself, but
it would be nice if someone else (you?) can test it.

Yes, that's a good idea.

Yes, that too. Not worth the trouble to find the reason in my opinion,
might need a lot of work.
