All this aside: you aren't seriously trying to talk this guy into using PAE mode, are you? Are you not, in fact, just being pedantic, yet agree with me on the most important point, which is that he should be using a 64-bit OS and application here?

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.
