To answer Pete's original question, I would suggest posting the patch to http://lists.infradead.org/mailman/listinfo/linux-pcmcia which is where PCMCIA subsystem development conversations are taking place. It might be good to cc: rmk since he's been the de facto PCMCIA maintainer.
Or, we'll go with your idea we just discussed :) No need for the 64 bit pcmcia patch in that case.
I'll make the updates in the next few hours and test them.
Pete
