Some Nubus card ROMs contain many slot resources. A single Radius video card produced well over a thousand entries under /proc/bus/nubus/. Populating /proc/bus/nubus/ on a slow machine with several such cards installed takes long enough that the user may think that the system is wedged. All those procfs entries also consume significant RAM though they are not normally needed (except by developers). Omit these resources from /proc/bus/nubus/ by default and add a kernel parameter to enable them when needed. On the test machine, this saved 300 kB and 10 seconds.
