Where exactly does it say that you have 2.2GB of memory available?
How much memory is available hasn't really got anything to do with how much memory Vista uses. Vista uses all the memory all the time, but has a priority scheme where a process with higher priority can steal memory from a process with lower priority. Then Vista also pads this with the pagefile where low priority stuff gets dumped onto the hard drive in case of a RAM shortage.
When talking about memory available you usually mean that something else is using the memory or the address space instead of Vista, i.e. integrated graphics.
