The answer was found in Sina's pdf and associated code
"Using ACC-5E I/O through Power PMAC"
The only other thing I had to do to configure the gpio ports for output was to set the buffer control bit for the appropriate byte.

I can't seem to configure any of the JIO GPIO bits for output.
Acc5E[0].LowIoMode=$ffffff;
Acc5E[0].LowIoDir=$ff;
Setting Acc5E[0].LowIoData does not change the state of any of the JIO bits.
They remain input bits.
What am I not doing right?
How do I configure Acc-5E JIO bits for output?

It was incredibly difficult for me to find the post with the desired attachments again:

The search terms that finally found it were "multiplexed" and "thumbwheel".
