I merged this into the acpi_video(4) driver (which already takes over ACPI devices with a DOD, etc. handle) so that the two drivers aren't mutually exclusive. Unfortunately, my laptop doesn't have any _DOD, etc. methods for its video device so I can't test it. It's somewhat hackish as only i386 has VM86 support, but the patch is at: http://www.FreeBSD.org/~jhb/patches/acpi_video_dpms.patch -- John Baldwin <jhb_at_FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.orgReceived on Fri Apr 30 2004 - 11:19:25 UTC
