o Convert length of hccb to integer from the array. Eivind Eklund 

pointed this out, but I've not seen a manifestation of this.
o Check against 0x00 as well as 0xff for geometry register, as some clone
  cards don't return 0xff.  Vadim Mikhailov pointed this out in PR
  8743 for his Dell SCSI Array controller working in AHA-1540
  emulation mode.  Note that this test is likely to go away in the
  future in favor of a better one Justin has recommended.
