Congratulations, I was playing with this a few months ago and failed to
manage to get video to play.

I would love to get hold of the source code, can we actually host it in
a source control system somewhere? I only ask because I think once the
ball gets rolling and this is exposed within OE more people will like to
play.

Even having vo_pxafb.c in OE monotone would be cool. Along with a patch
to plum it into mplayer build.

I maintain mplayer in OE and own a 3200 so Im quite happy to interface
between you and OE/mplayer.
