ACPI WDRT seems to be a very very rare beast.

Just in case, here is a my very hairy driver for watchdog logic and power led
control in Winbond W83977 family of Super I/O chips.
http://people.freebsd.org/~avg/w83977.diff
There are quite a few possibilities about how this chip could be wired and
programmed (e.g. watchdog output may go to any of three multifunctional pins), 
but
I really implemented only one configuration (the one that I actually had).
