HowTo: Get swsusp2 working

I recently got swsusp2 (aka software suspend 2, aka hibernation, aka suspend to disk) working on my acer travelmate 800 (a centrino machine). It has been working flawlessly so far, which is very good, considering that I never got swsusp*1* to work completely on this machine. All this on a 2.6.5-gentoo-r1 kernel, and following, the latest I've been playing with is a vanilla (standard) 2.6.7 linux kernel.

If you'd like to know how to get swsusp working, refer to this howto at the gentoo-wiki.

Supposedly the swsusp*2* code works much better, so it might really be worth a try.
