lets see what the more knowledgeable have to say:

CSSU-thumb
k-p 52 & k-p-settings
Swappolube
Flopswap or some such (2 swaps on mmc to deal with fragmentation)
720p libs

I would say that's it. Optimally, expect to reboot every 3 or so days. In my books, flopswap type approaches reap ample dividends if you browse a lot, open many windows etc
