Does anyone have any suggestions on how to get the full 8GB of RAM I 
have installed to be recognized by Linux?

The BIOS finds the whole 8GB (it's displayed on the BIOS GUI), Linux 
(Mandriva 2009.1) and Memtest86+ only find 4GB.

I suspect that this means that the BIOS is not telling Linux about the 
whole 8GB.
