The X-server needs root permissions to open /dev/mem. It's
always been that way. Either XFree86 needs to be suid root
or the wrapper does.
BTW, that error message is deceiving. You need to open /dev/mem
to map any of the card's registers, not just the framebuffer. And
even if it were a planar framebuffer you'd still need to open /dev/mem.
Somebody should fix that error message.
Mark.
