    I'm not going to say much about this apart from yes it is possible.

    Well done, you've presumably discovered the joys of Physical Address Extension, a feature that's been available since Server 2003 if you have the right hardware.

    That being said...you can't have a given application use more than 4GB of RAM, and while that won't make much of a difference in a system with 6GB total you can now buy high-end desktops from the likes of Dell whose motherboards support up to 24GB of RAM. And that's before you look at the high-end workstations whose motherboards will take up to 96GB of RAM.

    No this was not done via PAE

    If you use PAE on a 32bit system with 6Gb of ram you will be allocated 3/3.25GB ram out of your 6GB as 4Gb under x32 is the limit reserve is close to 800MB.

    No you won't. And yes it is PAE.

    I presume you used something like this - http://www.raymond.cc/blog/archives/2009/08/19/make-windows-7-and-vista-32-bit-x86-support-more-than-4gb-memory/ - which modifies the client Kernel to allow the use of PAE.

    Run BCDEDIT from the command line to see. Note the PAE : ForceEnable line and your kernel also isn't the default.

    Ha at least someone is awake here yes you are 100% correct :)
    It's done via a kernel modification, Well done on spotting it, time to blow this system away and re image it again.
