compcache needed for linux-ti-omap

[Paul Larson]

In the live images for ti-omap, on commonly available hardware such as the the rev c4 beagleboard I'm using, there is too little memory. 256M will allow you to boot the image and get to the gui, but when I bring up a terminal, I see that OOM has been busy killing things. Currently, I'm sitting at about 20M free. This will not be enough to run ubiquity and even running the live image is very tight.

I'm opening this as a placeholder for now, but I suspect there will be some other pieces needed to fully enable compcache.

Was able to get this running manually on the omap live image to create a small working compcache swap as a proof of concept. To do it correctly, we'll need rzscontrol packaged and included, and load the modules, initialize the ramzswap device, and enable it early in the boot process.

There existed two version of compcache in the kernel. We will stick to the one in the ubuntu/ dir from lucid instead of enabling the one from the staging tree in 2.6.33. The maintainer says the upstream version is not stable yet anyways.
