Is there a PAE kernel available?

Code:
ehnde@bt:~$ apt-cache search 2.6 | grep linux | grep server
linux-restricted-modules-2.6.27-11-server - Non-free Linux kernel modules for version 2.6.27 on x86/x86_64
linux-restricted-modules-2.6.27-7-server - Non-free Linux kernel modules for version 2.6.27 on x86/x86_64
linux-restricted-modules-2.6.27-9-server - Non-free Linux kernel modules for version 2.6.27 on x86/x86_64
This is all I found that was even close, and I hesitate to install a kernel version older than what is currently installed by default. These are also 64 bit kernels...

I just need PAE to use all of my memory - I've got 4gb, but am only seeing 3gb available:

Code:
ehnde@bt:~$ free -m
