it was only a couple of hours old at that point.  i tried with both 1GB
and 512MB installed, and also by disabling the hack to find all the memory
that the prom didn't tell us about.  same problem.

i'll try updating this.

both.  didn't matter.

i haven't booted this system since april 2008, but yeah, it very much
worked in the past, and the old install works (netboot or disk boot.)

nope.

i've seen panics like this on my netbsd-5 amd64 desktop.  my netbsd-5
tree has extra instrumentation around the code here, it shows that
an alloc fails, and then the code goes bad.. but i haven't figured out
much more than this about it yet.

thanks.
