A little old, but not /that/ old.  You do need to install RH's
'hugemem' kernel if you have more than 16GB of memory, but less
than that works fine with the stock kernels.  The RHEL3 box I just
checked here in the office is running the standard SMP kernel and
sees and uses all 6GB of its memory just fine.
