Check out arch Linux for arm at http://archlinuxarm.org/
They've got a really awesome walkthrough and several guides. Not to mention they are constantly updating and expanding the packages available. I installed it on my pogo and haven't looked back.
Work: Dell Optiplex 960 x3 on a KVM.
Room(Afghanistan): Dell Mini 10v Hackintosh / Asus EEE Box PC running Win 7 / Ubunutu 10.04
Home: iMac 20" from a couple of years ago / PowerBook G4 12"
The worst of them all is the freakin Dell Optiplex's at work, but what can I do? I love the portability of the Hackintosh and am thinking of installing Ubuntu on it as well, but I do love my Mac OS X.
