cg14 and SX aren't the same thing.
SX is a rendering engine soldered to the mainboard, cg14 is a VRAM  
module with a fancy DAC bolted to its side. The SX can render into a  
cg14 or main memory, it doesn't distinguish between them at all.
We know how to handle a cg14 - it's just a semi-dumb framebuffer  
after all, but we do not have the tiniest shred of information about  
the SX which is why we don't support any acceleration on it.

I sent a request for docs, among others for the SX - the only  
response I got was a message stating that my request has been received.

have fun
