What monitor model is it precisely ? I fixed a problem at one point that
was causing exactly that behaviour on my Apple Cinema HD display. The
problem was that the driver was leaving the i2c lines used for DDC in
the high state. I put them back down at the end of the DDC procedure and
that fixed it. Now it's possible that this change got lost ...
