  Didn't even get through psycho_attach().  I was on my second pass  
of printf()s having gotten past all of the ones I put in on the first  
pass, and suspected what I ended up finding when I saw the comment:

                 * XXX Not all controllers have these, but installing  
them
                 * is better than trying to sort through this mess.

  Putting printf's between each of the psycho_set_intr() calls shows  
that it stops in:

                psycho_set_intr(sc, 15, psycho_powerfail,
                        &sc->sc_regs->power_int_map,
                        &sc->sc_regs->power_clr_int);

  I'm about to trace into psycho_set_intr() to see if I can learn  
anything else, but does this indicate to anyone why this would be  
failing now (after 4.99.72, in netbsd 5.1_RC1 and 5.99.29), or any  
other suggestions to try.

  Let me know, and I'll see what else I can see.  Interestingly,  
turning on DEBUG and setting psycho_debug to 0xff to see everything, I  
see that the psycho_dump_intmap() doesn't seem to show things in a way  
I can decode.  And, I don't see anything that I can recognize as being  
power_int_map.  Of course, I think I just don't know how to decode it,  
but in case anyone else does, I'm seeing:

  Thanks all.
