I gave the kernel modesetting option a shot. It actually appears to
get me to a framebuffer much smoother than the previous method. I have
a good looking 720p framebuffer on the CRT port that I can play videos
with. I am quite happy about that thanks.

I have a HDMI port attached to the same chip, using DVO port C. Using
this port has much different results than the CRT port. I looked
through the DMESG and the kernel code and it appears that all non-crt
ports do not support mode switching.

Is there a hardware limitation reason for this?

I commented out the line in the kernel intelfb driver that disables
mode switching for the non-CRT ports, I had no luck (thought I'd give
it a shot just in case).

Anyone have an idea what it would take to fix this? I would be willing
to give it a shot as this box will ideally hook up to a tv using HDMI,
not a CRT monitor. I just need an idea where to start.

Thanks,
Jon
