Description

It seems from the console output I noticed in Bugzilla that we currently run
the video at a 60Hz frame rate.

Will the panel allow to reduce this to 30Hz? Not only will this help with
power consumption but it will reduce the reservation of the memory bus for
video data.

I have this bug block #1067.

With this patchset,
http://lists.openmoko.org/pipermail/openmoko-kernel/2007-December/000322.html

pclk can be dynamically adjusted in userspace using fbset. This may be helpful.

There's no real chance of this, the lower frame rates we looked at while researching the flicker issue cause flicker themselves.
