Old claims about embedded systems does not apply anymore these days
IMHO. Your omap3 board has lot more torgue than the systems X11
was designed for back in 1987 :-)

Would these instruction be helpfull: ?
http://linux.onarm.com/index.php/From_scratch

It's a step-by-step guide to build gnome based platform from scratch for
Omap3-evm board from Mistral.

It should have all the issues you are running into already solved
and EVM is one of the reference boards for the platform.

After you have this up and running, it's easy to evaluate if it's the
right choise for your needs.

It also contains Matchbox which is a window manager for embedded
systems with limited screen space.
