Since all the SVM processors are in a new socket, it's pretty sure that
the BIOS is compatible with the processor, since this is the first
generation processor for the new socket. 

Obviously, this doesn't take into account buggy or broken BIOS's, or
other bugs that may happen, but there's no "designwork" needed to make
AMD Virtualization work, there's no bits to enable, and no reason why it
shouldn't "just work". This doesn't necessarily mean that no-one will
ever find a combination of processor and board that won't work, but
since it's nothing actually needed to be done in the BIOS, it's not
particularly difficult to implement, so most BIOS-writers should be able
to get it working... ;-)
