Linux has been able to do this for ages, but it has been considered a
bad idea, because it wears the memory sticks flash.
In theory all it takes is:
1. # mkswap /dev/sdX (where sdX is your memory stick)
2. Edit your fstab to say:
/dev/sdX none swap sw,pri=2 0 0
UUID=stuff none swap sw,pri=1 0 0
instead of
UUID=stuff none swap sw 0 0
3. # swapon -a

If it is really the case that newer memory sticks (or the ones specially
made for ReadyBoost) don't wear fast from doing this it might be worth
to implement a GUI that makes doing this easier.
