There's the big start of SDL|ES and GLUT|ES for any platform that was done for the N800. I've got the code for those in hand and I suspect there won't be much needed to polish them up, forward official patches for SDL, start up an official FOSS project for GLUT|ES on Savannah or Berlios, and then make bitbake recipes for the intrim SDL|ES and the official GLUT|ES.
