I'm aware that KDE does create its own swap but does Hildon/Maemo use it? Anyway I had restarted my tablet at this point so KDE hadn't been started up again and it still reported no swap partition (as well as that 0, 0, 0 thing from free).

I'm wondering if there is a swap or not though (maybe it's just not being reported), considering some apps I run pretty much need swap or they would crash according to posters (e.g. wesnoth) and they seem to run just fine still.
