--- Comment #18 from Sanford Rockowitz <rockowitz at minsoft.com> ---
Here's a vote for getting some variant of the I2C speed change for DDC devices
into the i915 driver, preferably with a module option allowing users to specify
the speed to be used.  

Relatedly, it looks like the following change allows for adjusting the DDC/CI
speed for DisplayPort connected monitors, irrespective of video driver.  Am I
correct on that?

You're so right about marginal DDC/CI implementations.  For my personal rogues'
gallery see: http://www.ddcutil.com/monitor_notes/
