Well, I was using suspend2.net's page just as reference, to point out the fact 
that HIGHMEM is on both suspend "platforms" supported only up to 4G. 
I was not refering to suspend2's actual features, but rather swsusp's 
(or what's the proper name for suspend1 code). So i guess the patch still 
holds, no?

It works with HIGHMEM but not HIGHMEM64G. You can find the oops from 
HIGHMEM64G below. It crashes very reliably on little stress after resume.
