Hi, is there any chance (if yes, how to do this?) to use the xf86 driver which "provides access to the memory and I/O ports of a VGA board and to the PCI configuration registers for use by the X servers when running with a kernel security level greater than 0" in FreeBSD*? Then it will be possible to start X environment with a kernel secure level > 0, right? Normally it is impossible because of /dev/kmem etc. access. It is default solution in OpenBSD, I guess. Hmm, I see, that there is not xf86 in /dev directory, but... I know, that there is already a couple of xf86 drivers (e.g. xf86-video-nv, xf86-video-intel or libXxf86vm etc). These drivers are not right/required/correct, right? Of course I can change this level after system and X's start, but it is not the point. Is there any solution? Best regards!
