Sorry, I just got all these emails. I have shifted
projects, doing the accel work is back burner for me.

If you connect VGA out rgb with scart in rgb of a tv and join vsync and
hsync
thrugh 2 resisors of i.e. 120 Ohms to csync you should get a syncronized
video on the tv screen (after playing with fbset). This should be possible
with every framebuffer driver supporting tv timings. ctfb does and i810fb
does it also now. I'm sure, matroxfb and many others do also the job.
Programming additional registers for a separate video-out is not that
terrible - the interesting thing here is the interface if you do not like to
use special ioctls.

> * Video input (double ugh!)
see http://www.visuelle-maschinen.de/ctfb/fb/video_in_ct69000/ctvi_0.21/
before starting with that - the code fragments may help a little bit.
