OMAP3 contains a revision of the SGX where there is no 2D unit.

2D is a subset of 3D which happens to have Z=0

Before using hw-accelerated compositing we actually had a framebuffer based 
solution which would re-draw all the screen everytime a single pixel was 
changed.

Not very performing.

So, yes, it can be done somehow, but most likely someone should spend some more 
time working on it and anyway all the remaining sw stack would be probably so 
slow to be unusable.

Not very attractive ... i'd rather have just a shell prompt.
