and tables to map fimware names to driver names. Based on a suggestion from Eduardo (quite some time ago). Each device (on busses we can handle and care about) gets a device property storing the devices OpenFirmware package handle. To match the boot device, the phandle of the chosen bootpath is compared against this property, plus some additional string matching for disk/cd devices (where OF only provides a node for the device class, not each instance).
