What CPU revision is this ? HY-D1 ? I think there's not even a constant
in amddefs.h for it ? 

The last message seems to be from fidvid.c stage 2 . 
I'm very slowly looking at this code and it seems to be revision C3 and possibly 
others may be only half supported. In BIOS and Kernel Developer Guide (IIRC) There are a dozen requirements and I'm looking at the code
little by little to see if coreboot does it all. I've found or added code to fulfil the
first 5-6 but I suspect the other half may not be performed or not completely, 
and it may depend on the CPU revision (some steps are noops for some revisions). 
What I have is sychronized with svn from some weeks ago and it may not 
even compile, and it's also ugly and full of silly notes in comments, and not tested.
But I have little time for it so it'll take me a long while to finish if I ever do.
