Don't know... that's my question ;)

Well, it's the same function as graf_handle (AES 77). The only diff is  
that graf_xhandle set aes_control[2]=6 (instead of 5 for graf_handle)  
because graf_xhandle() returns "device-id" in intout[5].

If the AES doesn't support graf_xhandle(), i think that intout[5] will not  
be changed, and as consequence may contain any value....

best regards,
Arnaud.
