It's fairly complex. Let's just summerise it as "yenta texas instruments IRQ routing fucked up" 8) The chip has a bunch of registers to control what signals get routed to which physical pins, and it seems that between June 2002 and today, some bad changes happened. I'm currently trying to track down each one, but, as there have been several levels of patching going on, it isn't simple.

Yep, and I'm going to fix them as part of my present work.
Think about what happens to ->init with the current system when you have two different cardbus controllers in the same machine.
