  SVN rev 185007 on 2008-11-16 19:30:17Z by marius
  
  Use the spitfire VIS block copy/zero functions also with cheetah-
  class CPUs. In theory one could also use versions additionally
  taking advantage of the prefetch cache with cheetah-class CPUs,
  in my worldstone runs these either didn't provide extra speedup
  (USIII+) in comparison to the existing spitfire versions or were
  even slightly slower (USIIIi) though, so they aren't committed
  for now.
  The basic problem leading to the VIS-based copy/zero functions
  being initially disabled for cheetah-class CPUs was solved by
  letting cheetah_init() clear DCR_IFPOE.
