Why do you want to enable swap? Swap is disabled in NITDroid because it is not properly used by Android kernel and system AFAIK. See http://groups.google.com/group/andro...9c30688a?pli=1 and http://stackoverflow.com/questions/2...299813#2299813 (these threads are quoted in android 0.0.8 changelog near the point "* swap is disabled", here: http://forum.nitdroid.com/index.php?topic=315.0). The important part is the reposponse made by Dianne Hackborn:

It was designed with the assumption there would be no swap. Instead it
relies on an out of memory killer to remove background processes when memory
is getting low. Having this behavior work well with swap raises a lot of
issues about how the two interact... to be honest, I would lean towards not
using swap even if you can because a swapping system results in a much worse
experience (delayed UI response) than one where background processes are
killed.
Note that we *do* rely on paging, just not swap.
