Actually it looks like "s3 bios" is just a POST of the video card when resuming - you might want to try setting the sysctl hw.acpi.reset_video to 1 and see if that helps. If you're running amd64 and get a reboot with reset_video=1 then it might be worth commenting out the "int 0x10" line in sys/amd64/acpica/acpi_wakecode.S because it assumes the video is up and running by that point - which on some system's it's not. -- Bruce Cran
