The camera on the FSL BSP works fine with no hardware modification on
the mx35pdk.

As I suggested previously you should control the power rails, i2c pad
settings, etc from software so that the camera can also work in
mainline without the need of changing the hardware.

Do you have this patch applied?

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=f910fb8fcd1c97788f2291c8646597bcd87ee061

Also, try to isolate the display from this issue. Capture the image to
a file and try to play it on a PC.
