So your 3.3V is good and you just need to worry about the +2.5V?
If your -2.5V is good, you can take a wire and attach 1A to 1B and run with an unregulated positive rail (assuming you have no 2.5V regulator on the board). Might have a bit more noise, but it will work as the LMH6643 is spec'ed to run at up to +-5.
