Okay...

N32 is "32-bit address space, but 64-bit registers, 64-bit insns allowed".

In order to support the 64-bit registers and 64-bit insns, by definition
you have to have a 64-bit processor (R4000, R5000, etc.).

O32, the ABI that NetBSD uses natively, is "32-bit address space,
32-bit registers, 32-bit insns".
