The next binary release of XFree86 for FreeBSD will support memory
mapping the entire frame buffer in user space (the MITSHM extension).

You also need a kernel configured with the SYSVSHM (System V shared
memory) option.  The distributed FreeBSD kernel binaries don't include
it yet, so as it stands you'll have to compile a kernel for it.  Rich
