Yeah, you can kinda get it to work, I've got the same myself, but as its running OpenBSD, none of these tricks work... Open doesn't, as far as I know, have a working framebuffer console.
Check the gatos drivers:
gatos.sourceforge.net
And what the mplayer multimedia player has to say about framebuffer mode and s-video over at
www.mplayerhq.hu
