We changed (actually fixed) default SM_Key byte order. And saquery has
'--smkey' option now. I guess:

  saquery --smkey 0x0100000000000000 -m

. should work against old OpenSM.

Alternatively SM_Key value can be fixed in OpenSM config file (to be 0x1
instead of 0x0100000000000000).

AFAIR it is only "compatibility" issue.

Yes.
