For what it's worth, I've successfully used that tvp5151 board with a Gumstix 
Overo using the mainline kernel. Changes required to the OAMP3 ISP driver have 
been pushed to mainline. Some changes were required to the tvp5151 driver too, 
some have made it upstream, but I haven't had time to clean up and submit the 
rest of the tvp5151 modifications.

I've pushed the patches to

	git://linuxtv.org/pinchartl/media.git omap3isp/tvp5151
