That's because you're running out of address space, not memory. HIGHMEM doesn't do anything for the latter -- it can't. You start running into a lot of fundamental problems when your memory size gets in the same (or higher) ballpark than your address space.
The best solution is go buy a 64-bit CPU. There isn't much else you can do about it.
