There are some packages specific to slackwarearm that are floating around on the web that will probably help the pi run better:

I've not wrapped those into a module yet, but after you get more familiar with booting on the Pi and converting txz modules to xzm's (all you have to do us run txz2xzm) it shouldn't be tough to add them in. I'm leary to tweak too much without having the hardware in-hand.
