Let's see... Yes, the docs are quite confusing. 

As I understand, "nl80211" is not a driver "per se" but an API for 
drivers to use of it. It seems it will replace "wext" extentions and 
that's all its role.

If we continue reading, we get:

"All new mac80211 based drivers that implement AP functionality are 
supported with hostapd's nl80211 driver."

Note the "that implement AP functionality", because I think that's the 
key point here. So we if we go to the drivers table we can see that Intel 
drivers support "cfg80211" but not all modes are available.

Yes, that's right. I'm afraid your hardware/firmware combo does not 
support AP mode :-(

The "why", I dunno. Note that Broadcom cards (b43) or Ralink (rt2800, 
some models) also need a closed or non-modificable firmware but still 
they provide AP capabilities :-?
