Do you know what it takes to do it? How much work for a newcomer to get up to speed with gcc? (Maybe this should go to the developer list?)
You would need to write a memory allocator which divides the address space into 4GB (32-bit pages). Then you could create a new malloc routine which has an extra argument to allow you to allocate memory from within a specified 4GB page. That way you can make all of your allocations for a given data structure lie within the same region.
Then you can add the top 32-bits to pointer addresses within your data structure before you attempt to dereference them.
