>Description:
	I've made a new version of the XFree86 aperture driver. The
	new version takes into account modifications in the LKM
	framework since NetBSD 1.2 and adds support for Pentiums II
	and AMD K6 MTRRs, (from FreeBSD). This support will be used by
	XFree86 4.0 to enable write-combining on the framebuffer
	memory region (and disable it on the MMIO regions if needed)
	to improve performance. 
>How-To-Repeat:
	Try to build/install the current aperture driver from
	<ftp://ftp.netbsd.org/pub/NetBSD/arch/i386/apNetBSD.shar>
	under 1.4.x or -current. 

>Fix:
	The new version of the aperture driver is available on 
 	<ftp://ftp.laas.fr/pub/ii/matthieu/NetBSD/apNetBSD.shar>. 
	unshar it and read README for installation instructions.
