Double-check your arch manual. At least on alpha, we have a memory
barrier instruction that's not a nop (and alpha is similar to mips in some
ways, so I'd verify that). I have an R4400 manual around here
somewhere...if I get time, I'll look for it and look it up as well.

Is there a build log that everyone can look at as well? I have an Indy
with a monitor attached and I'd love to try X on it (my Indy is mostly
idle), so I can lend a (small) hand.
