6.8.2 is old, very, very old... I guess nobody remembers...

via driver in xorg 6.8.2 is unichrome r30. see unichrome.sf.net.
Don't remember about 3D, might even be completely broken, really don't 
remember... xorg 6.8.2 contains something like mesa 6.2.x

3D at least has seen a complete rewrite since 6.8.2. Support is much 
better now.

2D will only need 800x600x16 bits so 8Mb will be enough
3D depends on the number of texture you will need.
I might be completely wrong here...

via_dri.so is even older than unichrome_dri.so

why are you stuck ? I agree that moving to 7.0 (modular) is a lot of 
work, but 6.9 is not that different than 6.8.2. You can easily patch in 
openchrome in either one and make some updated packages, while still not 
breaking dependancies.
