I think the last working version was a little older than that -- and it's quite
possible that there was underlying badness even earlier that just recently got
exposed.  I think I want to just debug it and find out what's really going on.

That would be good :-)

I've been itching to do that but without HW it's not trivial :-)

Meanwhile, how about the tlb asm you promised me? :)
It will be a challenge I think since you only have 2 GPRs
I guess it would be possible to stash yet another reg since it
will fit in the cache line already used by the TLB handlers.

Let's just get it working first :-)

Ben.
