/me goes and swaps in all the details from the discussion at that
time.... tries to decipher what the whole story was about...
Well, AFAIR - the operative word being "remember" - Eduardo had a
problem with diffentiating between emulated features and real hw

I think we remained at that someone, maybe he, would have to clean all
that discrepancy before we do the emulated gunk. Let me CC him.
