Well, this has nothing to do with GNOME, but rather with GNU/Linux.

Read the man page for fstab and swapon.  There is a setting for the swap
filesystem that you'll want to look at/specify called priority.  I'm writing
this from M$ Windows (since Evolution doesn't do anything good yet), so I
can't check, but I think that you'll want fstab to be something like
/dev/hda8	swap	swap	defaults,pri=1	0 0

If you want it to stripe, set them both to the same number, if you want it
to go to the second one after the first fills, set one to 1, and the other
to 2.  If they are both on the same hard drive, DO NOT STRIPE, it will kill
swap performance, and if you're swapping, you can't afford that.
