I have an old Dell with a 32-bit 2.33 Ghz T2700. Linux fully supports the GPU, and no issues with missing 32-bit packages on OpenSUSE Tumbleweed. It's a spare browsing / retro gaming machine hooked up to the TV in the guest room. For gaming, it runs everything from arcade MAME to Mario Kart 64 like a champ. For browsing, it's not speedy but not bad on heavy HTML sites like gmail/youtube.

I agree antiX was a poor choice. No issue with PAE kernel on Tumbleweed i686. If OpenSUSE ever drops x86 support, there's always Debian or Arch 32 (if I want to stick with a rolling distro).
