I have read about the x32 port of Debian. Now, I wonder if Ubuntu has a x32 port or at least some x32 version of its packages since Ubuntu is based on Debian. It does have some libx32-* packages on the official repository. Can you have or build or convert an existing Ubuntu system to x32 (not really x86)?
There are reasons why. The available memory is about 1.8 GB, about 200 MB is used by the video card. The processor is 64-bit capable. I have custom compiled 64-bit 3.17 Linux kernel and packaged for 32-bit dpkg and it runs.
