That freestone piece of crap didn't work for me, and looking at the code I'm not surprised. I did a patch against the existing advantechwdt since the newer advantechs use the w83627hf. http://www.pixelbeat.org/patches/advantechwdt.diff I think the advantechwdt.c should be renamed to w83627hf_wdt.c to avoid confusion (or replaced with the w83627hf_wdt.c you referenced above, that I didn't notice when I did this).
Pádraig.
p.s. I needed to merge the info from a couple of different winbond manuals to do the driver. Note also the advantech manual describes the wrong watchdog!
