I don't think so.  The CPU support is not too much different from
generic r4k CPUs though.

It looks like a Malta board with MIPS32 CPU.  It appears netBSD already
supports Malta (under arch/evbmips/malta).

BTW, I am new to netbsd.  Take my comments with caution.  I know about
those boards because I ported Linux on them.
