swap versions?

[Net Llama!]

2.5.x & 2.6.x kernels require swap version 1.  What I can't figure out is 
what's the difference between swap0 & swap1?  I've googled a bit, and there 
are tons of instructions talking about how this version or that version are 
needed with kernel f00, but still no one explains why version 1 is an 
improvement over version 0.  Anyone have an explanation, or a pointer to one?
