  There are two ways to allow XFree86 to access linear memory:

     1. Disable the kernel security feature by initializing the
        ``securelevel'' variable to -1 in /sys/kern/kern_sysctl.c, line
        205 and building a new kernel. For more informations, see the
        comments in /usr/include/sys/systm.h.

     2. Install the NetBSD aperture driver:

        a. add the following lines to the end of /etc/rc.local:

              KERNDIR=/usr/X11R6/lib/X11/kernel
              if [ -f ${KERNDIR}/ap.o ]; then
                modload -o ${KERNDIR}/ap -e ap -p ${KERNDIR}/apinstall ${KERNDIR}/ap.o
              fi
--

I defined HasNetBSDApertureDriver YES, and thought everything was cool. But.

I never saw the aperture driver built. Is it part of X11R6? I can't find it.

I used method 1, and it worked.
