No, this does not prove anything. If you want to prove that 1.4.2 does
not have a fatal bug for the _Host AP_ mode, please feel free to either
implement or at least describe a generic workaround needed for the issue
of not processing Probe Request frames in the AP. As far as I'm
concerned, there is no way to work around that issue without changing
firmware code. Yes, you could change all stations to work without active
probing, but I would not consider that to be realistic solution.

Maybe they do not have the firmware they want to use in the AP available
in a form that can be written into flash. They would thus need to load a
RAM downloadable firmware and could not care less of what STA firmware
version actually is in the card since it would not really be used.

No, but it can be one without being in _Host_ AP mode. You might want to
learn about the other AP mode that is actually used in many (most?) APs
based on Prism2 cards. That is so called firmware AP mode, in which all
the IEEE 802.11 management operations are actually performed in the
card. This mode uses "tertiary AP firmware" which is only available in
RAM downloadable version..
