Looking at the manual on the HP 59306A, it says of the EOI line "Not 
monitored or driven, terminated by resistive network". This rather 
suggests to me it will make no difference whether the EOI is asserted or 
not and so whether I open the device with

dd=ibdev(0, gpib_address, 0, T3s, 1, 0);
dd=ibdev(0, gpib_address, 0, T3s, 0, 0);

will make no difference.
