I stripped forum from the reply since devel is more appropriate.
The reason why this doesn't work reliably in the "nv" driver is
because there is not an I2C bus - there are THREE of them - and it's
not clear which one the driver should be looking on. They're not
even the same between one card and the next since different board
vendors can lay the cards out differently. If I know the correct
bus, detection of the flat panel is trivial.
I am looking into this problem, but I'm not familiar with
XFree86's DDC code, and haven't found someone who is.
