I have tested AP mode on rt2500pci and rtl8187, both don't work at the
moment.

rt2500pci works best, but hangs somewhere in the
handshake/authentication process (I've posted logs on this list). I did
manage to get it to work beginning of Feb. this year, I'm still trying
to find the regression. Unfortunately the rt2x00 code has changed a lot
since then, and I'm extremely busy at work, so I haven't made a lot of
progress there.

rtl8187 does not come very far at all, hostapd can't switch it to master
mode apparently.. haven't investigated very much why this happens
though.. so it might be something trivial.
