The hardware watchdog is handled by OMSA and do 'omconfig the 'esm.o' kernel
module it provides.  It doesn't use the Linux kernel standard watchdog
functionality, so no /etc/modules.conf changes are needed.  Install OMSA,
then see
for an example on how to make it work using the 'omconfig system recovery'
