  SVN rev 190682 on 2009-04-04 00:26:01Z by nwhitehorn
  
  The Serverworks SATA chipsets used in Apple G5 systems require requiring
  the ATA status register with a 4-byte read request. This updates it, and
  subsequent 1-byte reads will return the correct result.
  
  This commit adds a hack to do this, which is currently ifdef'd powerpc,
  although Linux and Darwin do this unconditionally on all platforms.
