This might be a problem with the ichwd at this point.  I grabbed the 
original watchdog kld from,

http://freebsd.tamu.edu/wdog/

and applied the following patches

Loading just this module and then using watchdogd -t 10 and then a kill -9 
of the watchdogd program and the box reboots about 10 seconds later.  With 
icwhd, no reboot.

And I can get the i8xxwd kld to work just fine without having to put 
debug.acpi.disabled="sysresource" in /boot/loader.conf


Also, why are there 2 watchdog programs in the base ?

releng5-865# which watchdog
/usr/sbin/watchdog
releng5-865# which watchdogd
/usr/sbin/watchdogd
releng5-865#
