I hope he is not. Based on real world experience with running Oracle RAC 
on RHEL with 16 CPUs and 16GB memory on a NUMA machine, I would 
discourage anyone running PAE on systems with much more than 8GB.

Basically, for any RDBMS server, I would go 64-bit even if your machine 
only had 4GB memory (or 2GB)... almost for sure your database will need 
more memory sooner rather than later, and 8-16GB memory on a RDBMS isn't 
that much anymore.
