Yes, we switched to that from classic swrast on the grounds that 
llvmpipe is more like r600/nouveau (since almost everything but the 
actual code generation step is essentially shared) than swrast was like 
intel (where you'd basically never hit software fallbacks, so how do you 
have any idea how well the software path works).

It works shockingly well, though I don't have it working to the point 
where performance numbers are appropriate.  But as a back of the 
envelope kind of estimate, we're hoping 10x7 or 12x10 in a VM on a 
modern machine should be entirely usable.

Again: not working, don't quote me, etc.
