5.1R: page fault from AcpiNsMapHandleToNode

Hi,

I recently upgraded my Compaq Evo N800w to BIOS F.12.  After applying
Magnus' patch from acpi-jp 2190, ACPI now works - somewhat. Fan control
works, battery, special keys are recognized, battery/AC is displayed but
battery level is invalid. Suspend works but resume locks up.

Well last night after some 17 hours of uptime the system paniced
unattended.  Below is what I got out of the dump.  System is FreeBSD
5.1-RELEASE.

-- 
Grüße,
Georg.

Btw I already send this via WEB mail, but couln't find a trace in the
list traffic so I resend it here.
