I thought PAE was a kernel-level default install?   And that x86_64
didn't need it anyway?    Akkana, are you installing the PAE package
on a 32-bit machine?

On Fedora, "yum list all \*pae\*" and (\*PAE\*) lists nothing.

I guess since PAE requires an additional level of address translation
that it could degrade performance in situations where memory usage
never exceeded 3 GB and swap was rarely used.    Are there such
desktop systems any more though?
