To sum it up, Cardbus bridge is not a viable solution on Au1500 for
hotswapping devices, since any decent one (bus mastering) will not
work. USB2.0 should instead work with PCI based controllers, that must
be connected to the main PCI device (directly to Au1500).
Well, I think that this closes the issue. As a last note, Au1200 is not a solution since we really need PCI.
I'd like to thank everyone here, you've been very patient with me. :-)
