actually, I think that while you may be able to get away with only one

netfilter, use SLOB not SLAB/SLUB, etc). also keep in mind that each
module that you load wastes apartial page of memory.

No highmem? No thanks.

I really want hibernate to save stuff from above 1GB as well
as the stuff below 1GB.

oops, good point. I was thinking that the hibernate kernel wouldn't need that much ram for it's own operation and forgetting that it needed to access everything the main system had.
