They do give us fusion hw; before launch even.  That's why we had
Linux support before hw was available publicly.  My board just
happened to get bricked recently during a failed bios upgrade.  A new
one is on the way.  Also we are looking into a potential release of
UVD, but unfortunately, our decode hw is intimately tied in with our
drm implementation and if someone managed to use the released
information to compromise the drm in our windows driver it would very
negatively impact our ability to sell into the windows market and
would probably get the open source graphics initiative shut down.
