"The Silicon Motion SM712 is a PCI-based 2D graphics engine with 4MB of embedded video memory and a maximum output resolution of 1280x1024"

-> plug a reasonable GPU card into the box and deactivate that chip - it's not capable of things like celestia at all but rather a minimum hardware to get pixels onto a screen.

Also, OpenGL on siliconmotion chips seems virtually unavailable - there's apparently no kms or dri or gallium for that family.

Install MESA ("libgl-mesa") and you should be able to use software rendering (gallium on llvmpipe), but you'll have to ask your distro whether and by what package they support plain software rendering - but be prepared that it will be CPU intense and very slow.
