That means you must be running a PAE kernel (I suspect that the server
kernel includes this). This allows 32bit installations to use more than
3.2G of ram, at the expense of some additional complexity in the kernel.
It doesn't, asaik, allow a single process to use more than 3.2G of ram
though. That I believe is impossible with a 32bit kernel.
