Typically Linux hackers can hack the kernel to use very large RAM. Current applications are built to access up to 4Gb RAM at a time only. For machines with RAM of more than 4Gb you need to verify that the CPU comes with Physical Address Extensions (PAE). Call Intel to verify this CPU is with PAE. So, now its the Linux kernel that you need to turn to.
CentOS 5.1 64 bit should not have this limitation. However, the following method allows up to 64Gb out of box for CentOS 5.1 32bit (u can try this if the 64bit didnt work out).
You are missing the point about the bug in some Intel chipsets. http://www.google.com/search?q=intel+chipset+kernel+4gb
