You will need (at least) the following fix in hostapd to get this
working:
http://w1.fi/gitweb/gitweb.cgi?p=hostap.git;a=commitdiff;h=1c766b094a82a669a1d0bb7f8d132b322e56e81d
I have not tested whether this actually works, so no guarantees on that
being the only remaining issue.

Thanks for the hostapd patch (even better thanks would have been given
should it have been sent to the hostap mailing list or me ;-). It is now
in the current development (0.7.x) tree for hostapd (with the additional
fix I mentioned above). If you can test one, it would be interesting to
hear whether VLANs are actually working now.
As far as the kernel oops is concerned, that does not sound good..
hostapd should not have been able to trigger such a thing even with the
not-yey-fixed driver_nl80211.c.. Some more details on this could be
useful if I cannot easily reproduce the oops.
