Yes, that was written when Prism3 did not yet exist and has not been
updated since ;-).

Host AP driver has always supported Prism3. There are no major
differences between Prism2, Prism2.5, and Prism3 as far as the driver is
concerned.

Which firmware version are you using? If it happens to be STA f/w
v1.4.2, you should note that it has a known issue of not working in Host
AP mode. If it is another version, please do give more details: test
latest CVS version, send 'dmesg' output of a client trying to associate
with it. In addition, include full description of the card you are using
(vendor, model, firmware versions, pci/plx/cs).

It already supports Prism3. I use Prism2, Prism2.5, and Prism3 cards
in my tests and they all work fine. I am not aware of any Prism3-related
issue in the driver. You need to give more details about the issues you
have seen in order to make it possible to figure out what is wrong.
