I can't answer your question as to where to find this information, but I
have been down this road before, and I never found a satisfactory
solution.  If it's possible, my advice is to buy a regular wireless
access point and use it in bridge mode and hang it off of an ethernet
port.  It probably won't cost much more than a good, known-to-work,
Linux-compatible USB wireless adapter.
