The machine in question is a MSI Hermes 845GV (not the "-lite" version).

Ok, the i845 has a Chrontel CH7009 chip connected to it. This is a DVI
and TV-out encoder. Apparently it is in this chip that you would change
from NTSC to PAL mode.
Now, if I just had a FreeBSD program to do that...
Intel's developer pages for "Intel Extreme Graphics" lists selection of
wrong TV standard (NTSC / PAL / SECAM) as the most likely cause when you
get a black and white picture on your TV.

Any hints?
