Paul also pointed out that the kernel must be enabled for PAE.

Check /boot/config-2.6.[mumble] for the parameter CONFIG_X86_PAE .
If that is not there and set to "y", then the processor's PAE
capabilities are not engaged.  There are probably other associated
options that must also be configured.  The options are not in my
ancient 2.6.18 kernel.  They probably will be when I upgrade
distros.
