In earlier versions, swsusp required swap to be physical RAM + video RAM. And the recommendation was to make it a bit bigger, er, Just In Case. The suspend2 HOWTO[1] says requirements for using the swapwriter are spare swap = physical RAM. That's spare swap. The kernel will do its best to free up buffers and swap pages back in to make room for the swapwriter if it needs to. But yeah, sure, double your RAM to be on the safe side. I didn't know swsusp had a filewriter method these days. If I were setting it up right now I'd probably prefer going that way - relying on having enough free swap to suspend sounds kind of fragile.
