so in theory you can use a Bluetooth 2.1 controller and an AMP driven in
software by mac80211 and you get a Bluetooth 3.0 + HS system.

There are Bluetooth 3.0 controller (note the missing HS), but the
difference to 2.1 is only an extra HCI command and some unicast support.
Otherwise they are the same. For a 3.0 + HS system you need a WiFi
controller that can act as a AMP as well. So essentially you see two HCI
devices. One will be the BR/EDR the other the AMP.
