Now the kernel is much happier.

With the new cardbus code, we use pci routing of interrupts. This is great for everything except fast interrupts for sio. : As Warner noted, we need to get the IRQ information from the cardbus : bridge; reading its assignment would be a start, but I'd put money on : needing to bring the PCI IRQ routing stuff back too. Routing over the pci INTA pin is a lot more reliable. Don't need to use the ISA stuff at all.
