  Log:
  MFC aac.c 1.137:
    Calling RequestSupplementAdapterInfo before RequestAdapterInfo appears
    to trip a bug causing the latter to return a zeroed struct
    aac_adapter_info.  This causes two issues.  One is cosmetic only --
    a verbose boot prints information about the controller, and shows all
    zero:
  
    aac0: Unknown processor 0MHz, 0MB memory (0MB cache, 0MB execution),
      unknown battery platform
  
    The second problem is that the firmware version information is stored
    away for aac_rev_check, for userland tools (like aaccli) to query via
    the FSACTL_MINIPORT_REV_CHECK and FSACTL_LNX_MINIPORT_REV_CHECK ioctls.
    When aaccli encounters this issue it prints
  
    Command Error: <The current AFAAPI.DLL is too old to work with the
      current controller software.>
  
    Move the RequestSupplementAdapterInfo call after RequestAdapterInfo,
    which seems to fix both problems.
