The 4GB limit applies to each process.
Not in vista, 32-bit. XP could use PAE, but 32-bit Vista won't, which seems to be an artificial limitation.
Unfortunately I can't find a good link, but search the net and you'll find lots of people who have been trying to get 4GB to work in Vista.
edit: found a link.

32 bit address bus translates to 2^32 addresses, that much is true.
But, it doesn't mean that an OS running on a CPU with 32 bits address bus can only do 4 GB.
Here's how it can be done:

Solaris, Linux and Windows XP all support more than 4 GB of physical memory while being 32 bit for example.

The 4GB limit applies to each process. Even the original i386 processor could directly address 64TB of RAM.
