This is a bug in the way that the pccbb code allocates the register
window when it hasn't been set up. The "real" fix actually requires the
PCI code to configure the cardbus controller, but we don't do that yet
(we desperately need to, though).
As a workaround for you, though, try adjusting the memory that the driver
requests for the register window to be based at 0xf4000000.
