The pae-kernel never comes per d-u without the installed metapackage.
So show
Code: [Select]
dpkg -l | grep linux-image

PAE is *not* a feature that gives you any advantage by itself. It only allows you to use more than 3GB although running a 32bit kernel (without PAE 32-bit systems are limited to roughly 3GB)

So, unless you are running such a system delete the pea-kernel. Having it installed doesn't hurt, but does help neither.
Ok, you can't code, but you still might be able to write a bug report for Debian's sake
