I need to install a non-PAE kernel for a 64-bit machine that supports PAE. 32-bit 12.04 currently comes with a PAE kernel but I need to get a non-PAE kernel. An older version of Ubuntu is also acceptable as long as it runs in 32-bit mode.

It's as simple as doing this on your existing 32-bit 12.04 installation:
sudo apt-get install linux-image-generic
followed by a this to remove the PAE kernel (so the system boots from the non-PAE by default):
sudo apt-get remove linux-image-generic-pae
- Alternatively, comment out the
sudo update-grubto display the grub menu upon boot, from which you can select the kernel to use.
If you want to install a non-PAE kernel as part of a new installation, start with Xubuntu or Lubuntu 12.04 32-bit, both of which come with the non-PAE kernel. Once running, you can run
sudo apt-get install ubuntu-desktopto get the full Unity desktop experience.
In general, the two common kernel suffixes for 12.04 are:
-generic(non-PAE for 32-bit; standard for 64-bit)
-generic-pae(PAE and default for 32-bit only)
