I did have a qemu patch, but only enough to get a simple framebuffer running.

In the same way that we're missing bits of hardware to write a bios for, we're 
also missing bits of hardware for talking to the 3D engine.

I guess you could probably invent a simple DMA interface and feed ogsim 
commands over that. I wouldn't like to say whether that'll end up anything 
like the final hardware, but it might give you enough to take a stab at 
writing the rest of the 3D driver.
