Interesting; do you have a reference for this?  The programming manual
suggests that AP mode can simply be set like any other mode.  I've never
tried this, but I have used the extra "AP use" pseudo-BAP to poke around
in memory.

|The Cisco AP case has a CPU

If that's the case then the MC and UC boxes do it as well since I've been
able to set their device type to AP or bridge and they work fine. :)

|THe Linux driver does not do that, mainly because

It isn't clear that there is much to the API because the card performs only
the time-critical functions like sending beacons.  Most of the extra host/
card interaction has to do with PSP mode clients.  The host has to update
the TIM in card memory via the above-mentioned pseudo-BAP, but you can get
the address of the TIM (or at least its offset) from a documented RID.  There
is also a pointer to some Aironet extension information which is not described,
but you don't have to use Aironet extensions...
