 	I believe config can already handle orphaned devices.

 	We could do something like like having a GENERIC.in with

 	m4_define(`bus_pci', 1)dnl
 	m4_define(`bus_usb', 1)dnl
 	m4_define(`bus_eisa', 1)dnl
 	m4_define(`devices_pci_network', 1)dnl
 	m4_define(`devices_pci_audio', 1)dnl
 	m4_define(`devices_pci_scsi', 1)dnl
 	m4_define(`devices_pci_raid', 1)dnl
 	m4_define(`devices_pci_pciide', 1)dnl
 	m4_include(`../../../conf/devices.conf')dnl

 	devices.conf contains all MI busses and devices, with
 	appropriate m4 tests.

 	The bus_* defines would include the MI usb@pci, eisa@pci etc
 	attachments.

 	devices_<bus>_<type> would include all devices of that type

 	I've had a pass through the devices from i386 GENERIC and I
 	cannot get a result with which I'm happy.

 	Possible for that usage a better option would be to add code to
 	config.

 	The decision on the use of m4 vs cpp is in somewhat of an astable
 	state at the moment...
