Very strange indeed.  My RELENG_6 box reboots 
just fine with your version and the version from 
the PR.  However, the box fails to reboot running 
with a CURRENT kernel on either version of the watchdog.

On a chance, I tried a trick I used to have to do 
ages ago in order to get the driver to work.  I added

debug.acpi.disabled="sysresource"

to /boot/loader.conf

and then it worked on the CURRENT kernel.  i.e. 
kldload /tmp/ichwd.ko,watchdogd -t 20;killall -9 
watchdogd.... ~20 sec later, the box reboots 
running a CURRENT.  Without that in loader.conf, the box does not reboot.

I _dont_ have to add 
debug.acpi.disabled="sysresource" on RELENG_6 on 
the same box for the ichwd to work as expected.

dmesg.txt attached the for same machine-- running CURRENT, one from RELENG_6
