Using the wiring diagram posted by Johnnyapollo, I now have a REMOTE hatch release. Beware though - according to his diagram (and the one in the shop manual), the relay is behind the right kick panel - maybe my VX is bassackwards, but it was behind the left (driver's side) kick panel on my car. About a ten minute job, if you don't tear the wrong side of the car apart looking for the relay.

Now one press of the remote button unlocks both doors at the same time (how it should be IMO), and a second press pops the rear door - Fantastic!

The relay is in an access hole behind the LEFT kick panel. It's round like a turn signal relay, and is wrapped in a grey foam material. I just cut one of the lt grn/blk wires (got lucky, the first one I cut went to the passenger door), which on mine was the longer wire. I then ran a wire to the output side of my trunk popper (output side being the side with the wire that goes to the rear popper), spliced the two together, and wah la! Oh, and don't forget to splice the other two lt grn/blk wires together so both your door locks will work.
