Search the linked page for "CPUID manipulation program for AMD" -- there is some info about this. Apparently when run under virtualization, the CPUID instruction is intercepted and can thus be manipulated. There's also a github project for patching binaries generated from ICC to run the optimal code-paths even for AMD. But there doesn't seem to be a way to manipulate the hardware itself to change its vendor string.
