That was speculation on my part as to why bus mastering was not being explicitly activated (i.e. maybe somebody had problems with it). It may just be that the BIOS always turns it on for the PCI version so there was never a need to. Should we do this on uhci as well? Does anyone know if a such as thing as a cardbus uhci controller even exists? -Craig
