I have a 3Com 3CRWE154G72 Version 1 PCMCIA card. It works wery well with the prism54 driver (haven't tested it as AP). There is a version 2 of this card, and I don't think they sell V1 anymore. When I last tested, the V2 card did not work, but 5 months have past since that.
This card does not have the prism-chipsets you asked for, but I hope it helps anyway ;-)
