I would say the above gives sufficient hints at what is wrong...

driver here means the driver api layer within hostapd, not the device 
driver within the kernel. According to this table [1] iwlegacy supports 
cfg80211 so you should be fine using 'driver=nl80211' here. Despite its 
name iwlegacy is a relatively modern driver ;-)
