  SVN rev 215722 on 2010-11-22 22:13:26Z by marius
  
  - Fix and enable support for flow control.
  - Partially revert r172334; as it turns out the DELAYs in gem_reset_{r,t}x()
    are actually necessary although bus space barriers and gem_bitwait() are
    used, otherwise the controller may trigger an IOMMU errors on at least
    sparc64. This is in line with what Linux and OpenSolaris do.
