 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.
