A possibly related problem: When I insert the modem card, the kernel
puts it at irq 9, but setserial later thinks it's at irq 2. Maybe
some interrupts are getting cross-wired? Or maybe it's fine and I
just don't have the right conceptual model of how pcmcia and the
kernel parcel out irqs.
On the i386 architecture, when support for IRQ's 8-15 was asdded by
daisy chaining a second 8 IRQ processing chip to the first, IRQ 2 was
hijacked for this purpose, and the original IRQ 2 was mapped to IRQ 9.
This is inherent in the design of the ia32 architecture at this point.
