Swap file

I have /slatedroid firmware and 1.9drivers with the scroll vol button mod and it works great. Don't really want to mess anymore with firmwares as I ilk the way it works for an ereader. Now to my question. I want to integrate a 128mb swap file on this tab with out changing firmware. It may have been covered elsewhere. If someone can helpmi would appreciate it. I have gotten so much on this site to make this chinese craplet work pretty well. Thanks for your help.
