Well, I'd say the difference between ram usage on lean install
(base,xorg,openbox,lxde-utils) between i686 and x86_64 is kilobites.
In fact, after running one install, and deciding to go with the other,
there was at most maybe a 1mb difference.  Its not much. (with that
setup, right after boot would weigh in 99mb ram used :))

As long as you keep the base system lean, 1gb is tons of free memory
to play with.  Hell, I have Gnome/Compiz and a ton of firefox tabs
running, and only 1gb ram installed, and 380mb ram still free
(cached... but free) Also, I think the benefit of being able to run
x86_64 guests would outweigh any penalty you'd be paying in larger
address space.
