In my experience, on an average system with the usual applications installed, software such as antivirus and MSN running, and a couple of other applications open, it is not at all unusual to see less than 100mb left from an installed 256.
512mb is generally the optimal amount for most users and leaves a sizable portion of the ram in reserve.
Windows XP uses around 120mb on it's own, so that, together with an average 25/30 other processors running, bumps usage beyond the 150mb mark and not much left out of the 256 module for other things.
