Okay.  Here are some more details on the panics I see:

a. I was seeing them all the time at `shutdown -p', but never
    with `shutdown -r' (or at any other time, for that matter).
b. if I startup with ACPI turned off, I will not see a panic at
    `shutdown -p'.  Of course, that also means that the machine
    does not really power down by itself.  I would have to be
    present to flip the 'off' switch.
c. All of this testing has been done using the 'vr0' ethernet
    interface, which is on the motherboard that I have.  It happens
    that I wanted to have a second ethernet interface for testing.
    I added an PCI card with a sis0 ethernet interface, moved the
    ethernet cable to it, and changed rc.conf to use sis0.

    Since I switched to using sis0 instead of vr0 for ethernet, I
    have not seen any panics from doing `shutdown -p' with ACPI
    turned on.  The machine now does power down completely.

All of this is on RELENG_5_3, up-to-date as of about 4pm on Saturday.
