This patch makes all rt2x00 drivers tell mac80211 about possible
interface combinations they support. Only combinations allowed so far
are 4 APs for rt61pci and rt73usb; 8 APs for rt2800{pci,usb}.
The driver-specific code in add_interface is now redudant and thus
removed.
However, real-life testing on RT3052F SoC showed that neither WPA-PSK +
Open nor 2 WPA-PSK APs work properly (though both APs beacon properly).
No other tests were performed.

Gertjan, i hope this is what you meant, and thanks for spotting my
mistake.
It would be very nice if one of you rt2x00 developers tried multi-bss
now with this patch to see what might be wrong with the
driver. Testing it is really easy, basically, you just need to add
"bss=wlan0_0" to the end of the hostapd.conf and then to specify all
the other options (ssid, encryption) that are to be different from the
first bss.
