Pentium100, NetBSD/i386-current w/PMAP_NEW and UVM.  
System: NetBSD 1.3C NetBSD 1.3C (INTREPID) #1: Mon Feb 16 17:38:53 PST 1998 i386

	IPFilter 3.2.3 compiled as an LKM with -DUVM and -DPMAP_NEW in
	/etc/mk.conf causes kernel to crash when it's loaded.  The module
	appears to load, but then causes a dump with a UVM error message.
	(unable to copy down the message)
	LKM's in general work okay, as the Aperture driver loads and
	operates on the same kernel.
	UVM kernel loading ip-filter LKM.
