No need to rely on luck as (given that no single size fits all) we have the `hpbussize', `hpiosize', `hpmemsize', `hpmmioprefsize', `hpmmiosize', options to the `pci=...' kernel parameter for people to tune the settings according to their needs. I don't have such a CardBus option, but I do have a couple of such ExpressCard devices, and mixed PCIe/PCI expansion backplanes for them. Maciej
