	# With the b0rked modutils, "modprobe hid" does work. But if something
	# (like hotplug) tries to auto-load hid (because another module needs it,
	# via the kernel module auto-loader) and keybdev.o or mousedev.o don't
	# exist, then the "above" clause fails and the hid module never gets
	# loaded, and then things like USB will fail.  Thus we remove it all
	# together.

    #   1) we have no logging enabled

    #   2) our config file is /etc/modprobe.devfs or /etc/modules.devfs
