I'd say yes :)

Might be possible but not for SoC devices as they've got no firmware.

Maybe I'll give the "beacon slot usage without holes inbetween"-approach
a shot and see if it is feasible or not.

In the meantime to not leak any random memory content we could simply
initialize one more 32bit word to zero in rt2800_clear_beacon.

Maybe it's even possible to just modify BCN_OFFSET0 and
BCN_OFFSET1 to get the hardware to reorder the beacon buffers.
I'll give that a shot too ...
