The release notes for RHEL-3 do say the hugemem kernel is required for
more than 16gb of RAM (implying you can use a different kernel for less
than 16gb RAM) ... but the this is from the install RHEL-3 installation
manual:

"If the system is i686-based and contains more than 4 gigabytes of RAM,
install the kernel-hugemem package built for the i686 architecture as
well (the kernel version might vary)"

So, you might be able to install the SMP kernel with 8GB, or you can
install hugemem kernel.
