Biarch runs natively and therfore faster, it can use 
hardware-accelerated OpenGL, it is easier to setup and use, and it is 
fully supported by TUV. To me the separation of arcitectures is clean 
enough and you simply switch from 64-bit-mode to 32-bit-mode by typing 
'linux32'. How can it be better with a virtual machine?

Also consider for example a compute cluster. It will of course have the 
64-bit version of CentOS installed, but some users may also want to run 
32-Bit-Code on it (because it's faster in their case, because their code 
isn't 64-bit-clean yet, or because it's a 32-bit-only commercial code,
