For the record, I did:
yum install kernel-PAE
yum install kernel-PAE-devel
I already had akmod-nvidia installed. (Which rocks, btw.)
I knew that akmod-nvidia needed a -devel package because I used to
manually build my nvidia drivers. But I didn't realize that the PAE
kernels had their own -devel, but then I should have because its an
option in the kernel setup if you build your own kernel. DUH !

I've been running this installation since Fedora 8 and I think there was
a time period when the PAE kernels were not available. And everything
since then has been an upgrade/update, so Anaconda probably isn't
getting to look at what kernel I might need.

Everything seems faster, but I also changed kernels and there was a yum
update to KDE at the same time, so I can't tell how much is from the new
kernel version, the new kde updates and from PAE. In any event, I am a
happy camper.
Thanks for the replies.
