When I rewrote the machine-dependent parts of HP-UX 8.0 for the VM system, this is one parameter that I cheerfully nuked. In 8.0 (unless they've changed it since, caveat emptor) the default atach point for shared memory is the beginning of the second quadrant--a gigabyte up. Same story for mapped graphic frame buffers. I suspected that it would save people a LOT of grief, and this sure looks like one of those cases!
