base os + base x uses up about 10-12m ram. then u add WM and panels etc. so it
depends what you want to do/replace. i think all the base is about is about 31m
of ram as it stands (gtk+ base today, matchbox, mb-panel, mb-keyboard,
lock-screen app when it pops up). so thats what is paged in and needed in ram
other than buffers/cache. the rest is available (so lets say 90-95m) is what
mind u i am playing with a bit of gui fun that only uses 15-16m as a base
(incuding x and base os)... :)
