I don't know exactly what is implemented in FreeBSD secure
level's. The one I'm sure is that FreeBSD never forbid direct access
to the framebuffer using mmap(). FreeBSD (and Linux) don't need an
aperture driver for that.

Most modern VGA boards (in particular those made by Matrox) require
linear access to the framebuffer for the Xserver.
