I had this exact same symptom.  The solution in my case was to ground the PALS.
But this will not help you, because...

Wow! This is a new thing to me!  What type of hacks were performed to allow an
A1000 with NO daughterboard?

A1000's are famous for flaking out after more then one expansion device is
connected.  Typical solutions include grounding the PALS or replacing the PALS.
In your case (No PALS, I guess) I don't know what to suggest.  Good luck to
you.
