Your machine is fine. The limit for a 32 bit kernel is ~3.6G. Try
running a 32 bit hugemem kernel or an smp kernel that supports over 4G
(32 bit RHEL4 smp kernels do) and you will see all your ram. But there
will be a small penalty for addressing over 32 address space. That's
what 64 bit kernels are for.

If that is true, is that a linux kernel issue?  I put the memory into an old
dumpy Windows Millenium machine and it recognized 4032Mb RAM.  That has to
be bios/motherboard related, although I would have thought the asus server
board I am using would be better than the one in the Millenium machine.  The
ASUS board can't report close to 4 Gb even in the bios, before it ever gets
to the kernel
