chip crisis and ram optimizer apps

we are all affected by the crisis and so ram optimizer apps get more and more important. i was hoping to find here a opensource app. i found here nothing, besides maybe a discussion or request of RAMagic or so.
i had long time ago one but cant remember the name and try to relieve it else/differently.
if i get to and find a nice opensource app, i try to post a request, as RAMagic seem only freeware.
lets see if we get such an app in the repository soon to assuage the pain, i'm looking to it.
