Electronics (that is, solid state stuff like ICs, Transistors and microprocessors) tend to die a horrible and instant death under reverse-polarity conditions.

The news that others have recovered from this makes me believe that you have hope, but remember, OFTEN each circuit board will have a reverse-polarity protection diode that is there SPECIFICALLY TO BLOW FUSES UNDER SUCH CONDITIONS.

As has been said before, check ALL FUSES. That is, pull them out and LOOK to see if they are still good. The more blown fuses, the more likely the car was protected well enough to survives this!
