32 bit apps can only use 2Gigs of memory. Paging doesn't come into the equation at all.
Vista will only delete the paging file on reboot if you explicitly set the registry option forcing it todo so also 32bit can address more than 2gb of memory, physical or swap.
The paging file is very important on every windows OS because it swaps out all the junk it doesnt need to use, You can check the pagefile usage under the performance tab in task-manager. My comp has swaped out 1600M of junk it doesn't need and thats memory I could use for more important tasks like compiling, games or VTx/AMD-V Operating Systems...
I guess its just preference if you want to use the paging file or not but I have found Vista gets a huge performance increase using the swap than without one.
