	This assumes you have a copy of the NetBSD syssrc.tar.gz file
	extracted locally - otherwise you can work through the source
	at http://cvsweb.netbsd.org/
	Taking the AdvanSys ULTRA WIDE PCI SCSI controller as an example:
	a) Look for the device in sys/dev/<bus>/files.<bus> (in
	 this case sys/dev/pci/files.pci), or if it is port
	 specific (eg: the VAXstation 2000 onboard MFM-controller)
	 in /sys/arch/<arch>/conf/files.<arch>)
	b) The attach section should read something like:
	# AdvanSys ULTRA WIDE SCSI controllers
	# device declaration in sys/conf/files
	attach adw at pci with adw_pci
	file dev/pci/adw_pci.c adw_pci
	file dev/ic/adwlib.c adw_pci
	file dev/ic/adwmcode.c adw_pci
	 This defines the common backend (dev/ic/adw*) which
	 may be shared across multiple ports and busses, and
	 the bus specific frontend (dev/pci/adw_pci.c) which 
	 'glues' the backend driver to the bus.
