I'm not sure, but at least all Pentium Pro, -II, -III and -4 models.

And also all AMD Athlons from the first AMD K7-500 MHz.

Linux supports this only if your kernel supports it.
Perhaps you will need to rebuild your kernel.

But this is not recommended because there is huge performance penalty
from using over 4GB of RAM on 32-bit systems. (enabling PAE) - better
way is to use AMD64 instructions.
