I've picked this up.
With this patch and the one below I can get tv-out working on my very old
beagleboard, and it seems to work with X also. It doesn't start automatically
as the connection state is unknown, but doing "xrandr --output None-1 --auto"
was all I needed to enable it.

Subject: [PATCH] drm/omap: fix fbdev pix format to support all platforms
omap_fbdev always creates a framebuffer with ARGB8888 pixel format. On
OMAP3 we have VIDEO1 overlay that does not support ARGB8888, and on
OMAP2 none of the overlays support ARGB888.
This patch changes the omap_fbdev's fb to XRGB8888, which is supported
by all platforms.
