I've attached my KERNCONF.
AFAICR, I'm using this kind of configuration for vesa since FreeBSD 5.x and vidcontrol with MODE_ since when it was ported from DragonflyBSD.

I've added 
    device          dpms
    options         X86BIOS
just after running csup last time, as in /usr/src/sys/i386/conf/NOTES there is a comment stating that X86BIOS is required by vesa.
I'm not sure if that is correct.


Thanks
Barbara
