It depends on what you need the watchgod for. If you just need it to
recover from hardware/software hangs, then the internal card works
fine. If you are only worried about software hangs, then the software
watchdog timer that can be compiled into the kernal may do the job. If
you need a hardware watchdog, you can look at the addresses in the
watchdog.txt file included with the kernel docs. I did a search on the
internet and came up with http://www.outsrc-em.com/watchdogs.html. I
havn't tried them, but from the sire, it doesn't look like it would be too
hard to make them work with Linux.
