The framebuffer support in FreeBSD is pretty weak, look at the VESA
part of syscons. You might want to have a look at KGI too, but I'm
not sure if that is still actively supported. If you want to do more
work in that area, you might want to talk with Sascha Wildner from
DragonFly, he's been improving syscons lately.
