I think you are right nate. When I started with Linux a couple years ago, the 2.0 series was current (like 2.0.36 or something). It was then that I read in a how-to that even if you make a really big swap partition, only 128MB would be used. Last night I tried to confirm this with my current 2.

I agree that the 3x swap rule makes little sense on high end systems. A guru friend of mine explained it as "if the kernel needs to swap out your memory it might have to swap the whole thing so you should plan for that". He believes you should use 1.5x your RAM on high end sytems ( >= 32 MB). I
