Let me think about that.  Now may not be the right time, but I suspect
that I'll take you up on that offer in a few months.  In the meantime,
I'll say that I've always got prompt responses to my requests for
testing from people on this list, particularly jchandra@.  So, I don't
feel like progress on MIPS VM issues is being slowed much by my lack of
hardware.

Thanks,
Alan

P.S. I would encourage someone with hardware to look into implementing a
non-iterative ffs*() using (d)clz.  The MIPS pmap would benefit from
this.  Basically, most pmap_enter() calls are doing an ffs*().
