   And I seem to understand that David's preferred SUN hardware only
   allows streaming when using SAC with IOMMU.:-)
   
It is true.

   And using DAC is 1 PCI cycle lost per transaction and if we are
   picky on performances ...

True.  This is why I find it mysterious when I run across a device
which does not issue SAC for addresses with only 32-bits of
significance.

Happily, most do behave this way.
