insmod /lib/modules/current/ramzswap.ko disksize_kb=131072 wait a minute. does the n900 have 131mb free even after boot? and then we momentarily swapoff the default partition,so 131mb have to be real ram. very risky operations. are you sure with the above disksize we are not adding double that? is'nt the disksize the ram we are asking and not the target?
