Right, I was specifically thinking of the MIPS-II/R3000 ones here, I know there are users on multiple actively maintained MIPS-III platforms.
Regarding 32-bit vs 64-bit kernels, can you clarify what makes this one a 32-bit board? Is this just your preference for which kernel you install, or are there dependencies on firmware or hardware that require running this machine in 32-bit mode?
(MIPS is not my area anyway, I'm just curious)
