  Log:
  Do initial cut of SAS HBA support. These controllers (106X) seem to support
  automatically both SATA and SAS drives.  The async SAS event handling we catch
  but ignore at present (so automagic attach/detach isn't hooked up yet).
  
  Do 64 bit PCI support- we can now work on systems with > 4GB of memory.
  
  Do large transfer support- we now can support up to reported chain depth, or
  the length of our request area. We simply allocate additional request elements
  when we would run out of room for chain lists.
  
  Tested on Ultra320, FC and SAS controllers on AMD64 and i386 platforms.
  There were no RAID cards available for me to regression test.
  
  The error recovery for this driver still is pretty bad.
