Cyc III 780 Pin BGA (EP3C40780) complete list of pins affected: AC11, AF18, AH18, AH10, C25, G19.

BSDL files for all Cyc III devices on Altera's site are going to be updated to note the problem pins for each device; that they must be tested in post-config mode if current is needed above about 1 mA.
