Are you sure the driver you use supports this?

hostapd supports multiple BSSIDs internally (bss=<ifname> option) with
mac80211-based drivers. madwifi does not use this design; with it, one
would create the interfaces first and then run hostapd for each created
interface separately (i.e., not using bss=<ifname>, but multiple
hostapd.conf files).
