  MFC important fixes by sos@:
  Implement a workaround of the datacorruption problem on ServerWorks
  HT1000 chipsets.  The HT1000 DMA engine seems to not always like 64K
  transfers and sometimes barfs data all over memory leading to instant
  chrash and burn.
  
  Also fix 48bit adressing issues, apparently newer chips needs 16bit
  writes and not the usual fifo thing.
