I have, and I have disabled it from starting up.

I noticed that when running two or more large apps (i.e. canola, navit), while ramzswap was running, would see my n810 "bog-down" (get real slow) for several seconds. When I disabled ramzswap ("swapoff /dev/ramzswap0"), removed the kernel module ("rmmod ramzswap") and went back to using a dedicated partition for my swap space, things would run much more smoothly and consistently, even if slightly slower.
