From what I've read, x86 can address 4 Gb of memory,
so it would seem that more than 4 Gigs of combined memory and swap space
would be wasted. Am I right?

You would be right if all of the memory was only being used by one process. However, each process has it's own 4GB of virtual address space, although typically the top 1 GB is actually shared (ie, is used by the kernel), and other complications (like using SysV shared memory) can change this further.
