IMHO, you don't have a chance to do it without patching postgres or developing
your own low-level function.
Try to play with SP-GiST (http://www.cs.purdue.edu/spgist/) SP-GiST is a
modification of GiST for Space Partitioning Trees. But they patch will not work
with 8.2 and up because of lack of concurrency. 8.2 doesn't support indexes
without concurrency.
