I know 4gb is the limit for a 32bit OS but i thought it would be able to
use all of it? Is there another kernel i was supposed to install?
I've seen this before on laptops. This could be a limitation of the
chipset itself. If that is the case, nothing can be done about it.
Another option is that you try to boot with the PAE kernel. That
kernel is made to go over the 4GB boundary on 32bit.

destructs after migrating 2000 users over to it? ;)
