Lubuntu, PAE, and 4GB of memory

I'm running Lubuntu 14.10 on a Dell Optiplex GX270, with the max 4GB of
memory installed.  When I do a 'free -h' at the command prompt, it shows
max memory of 3.2GB.  Given that Lubuntu 14.10 requires a processor
capable of using PAE, you'd think it would use it to make use of that
other .8GB of memory.  Do I have to do something to enable that?
