Comments, David?
There are some people who use PCMCIA on SMP desktop boxes; many wireless network cards are only made as PCMCIA cards, and the "desktop version" consists of an ISA or PCI card reader plus a card.
It is not a configuration that I currently test. I am told it mostly works, though some client drivers are not SMP safe. It is something that should be fixed eventually, for sure, but given the number of open issues with PCMCIA in 2.4, I don't think it is high on the list. If you want to say that PCMCIA on SMP is unsupported until someone carefully checks it out and fixes these things, I suppose that's fine.
