video files differences in revb2 and latest git

       I wanted to check the video demo [stream_video using harry.yuv]
on the latest git-pulled from mvista [2.6.28]; but was unsuccessful.
But I saw that, revb2 kernel [2.6.22] it is working fine. I saw that
in revb2, /dev/video1 is up , where in latest git it is not. Also in
revb2, drivers/media/video/omap folder is present where in git-pulled
version it is missing. [I used default omap3_beagle_defconfig
supplied] Am i missing any video patches here? Do I need to further
enable the kernel? I Any info will be highly appreciated.
