the in kernel suspend uses swap, tuxonice can use either swap or file, don't
know about uswsusp. In any case there shouldn't be any problem writing the
suspend file to tmp because you are not actually shutting down and turning on as
far as linux is concerned.

I'm using tuxonice with nvidia (and so is nigel by the way, the maintainer of
tuxonice). Some cards do have the issue that it takes them about a minute to
wake up properly, so effectivity depends on how many programs you like to run

There is a catch that you require the shutdown method to be 5 IIRC (shutdown)
and not 4 (acpi suspend) which is the debian default.
