AMD Opteron D0 support

[yhlu]

Any one got D0 Opteron?

It seems that AMD put the D0 releated info in their BIOS porting guide
(PUBLIC Version). But didn't release new revision guide about that.

They are extremely rare. AMD usually sends us new chips fairly soon,
we don't have one yet. But Sun has submitted SPEC results already with
our compilers. Life is unfair!

Actually it turns out that we have 6 of them -- what would you like to
know?
