>Environment:


System: NetBSD slug 5.99.23 NetBSD 5.99.23 (SLUG) #42 Sun Jan 10 17:36:27 CET 2010  leo@slug:/usr/src/sys/arch/i386/compile/SLUG i386
Architecture: i386
Machine: i386
>Description:
	drm with modular-xorg-server doesn't work on intel i945 (at least with
	some bios releases). This is because the bios doesn't enable busmaster
	dma for the graphics board. In NetBSD-5 and NetBSD-current xsrc
	xsrc/external/libpciaccess/dist/src/netbsd_pci.c turns on busmaster
	dma. After dropping xsrc/external/libpciaccess/dist/src/netbsd_pci.c 
	into sysutils/libpciaccess/work.i386 and reinstalling libpciaccess
	drm works with modular-xorg-server.
>How-To-Repeat:
	Try to use drm on an optiplex 755mt and watch a black screen.
>Fix:
	patch netbsd_pci.c in the same way as in xsrc.
