ACPI causes page fault/panic upon reboot

Pete, I'm sending this again with a little more info.

When I get the chance, I will.  There were only two instances of
windows, and both were in the same block.  The second one was a test for
windows ME, and was nested inside the else of the previous test.  In
other words, if the first test succeeded, the second test never would
occur.  I suppose I could make it try to match the "Windows ME" block
instead, but somehow I doubt that will work, either.

I can't exactly capture the dmesg, because it doesn't boot far enough 
for it to get recorded.  I will type in the last bit for you:

Timecoutner "ACPI-fast" frequency 3579545 Hz quality 1000
acpi-timer0: <24-bit timer at 3.5795454Mhz> port 0x1008-0x100b on acpi0
acpi_cpu0: <CPU> on acpi0
Device configuration finished
procfs registered
Timecounter "TSC" frequency 664649328 Hz quality 800
Timecounters tick every 10.000 msec
lo0: bpf attached
Mounting root from ufs:/dev/ad0s1a
setrootbyname failed
ffs_mountroot: can't find rootvp
Root mount failed: 6

Then it asks for me to manually specify the root.  Of course, that is 
the right root slice, so there's nothing I can do.

That's what I thought initially, until I looked at the rest of the file,
and saw that *all* the Name clauses end like that, including two others
that I quoted already:

>> 123     If (S3EN)

>> 125         Name (_S3, Package (0x02)
>> 126         {

>> 128             0x05
>> 129         })
>> 130     }
>> 131     Else
>> 132     {
>> 133         Name (_S1, Package (0x02)
>> 134         {
>> 135             0x01,
>> 136             0x01
>> 137         })
>> 138     }
