The 32-bit hardware severely limits addressing beyond a 4 GB boundary. If
you want to handle more than 4 GB cleanly, you'll have to go to a 64-bit
architecture (which is coming, but isn't quite here yet).

The big problem is having a convenient way to address RAM directly. 32 bits
= 4 GB. Very much like the problem with MS-DOS and 16-bit addressing, which
required that everything be chopped up into 64K chunks.
