At the moment, there is no support for PCI-to-PCMCIA (16-bit-only)
bridges that are only wired for PCI interrupts. PCI-to-CardBus
bridges are ok.
The only exception is the TI PCI1031 PCI-to-PCMCIA bridge, which is
more like a CardBus bridge with some of the CardBus support disabled.
The 3.1.11 drivers try to support this (I don't actually have one, so
I'm working with someone to verify that this works).
