The idea is really good. Imagine using a chunk of your rootfs (say, 32MB) as compressed swap.
Not our kernel, a way newer one in mainline (and the Nokia kernel on the N9/50, 2.6.32)
The Mer kernel doesn't have it, the Mer-3.x kernel probably does.

Either way, it'll need to be backported to be used, and Maemo moved off the rootfs to do so.

(Side note: I actually tried booting Harmattan on the N900 using the MeeGo CE kernel. When booting back to Maemo, I noticed that everything was crashing randomly. #maemo said that it probably tried to swap on mtd5. Lucky that Nokia didn't use any other partition as swap, as that could've been nasty for my phone.)
