Can you give me more info?
I'me trying since days without luck to reboot my wrap wiht 2.6.12 ...
With kernel 2.6.8 from voyage reboot works without any watchdog
(i.e. I disabled watchdog in /etc/init.d)
Only modules are:
  dm_mod, natsemi, crc32

If I use my kernel 2.6.12 it will not reboot
With sc520_wdt running it wont reboot
with wd1000 (/etc/nodules) it reboots and when it is up will reboot again
If I have watchdog running wihtout wd1000 it won't reboot
if I insert wd1000 (modprbe) the following message comes:

wd1100: module license 'unspecified' taints kernel.
SC1x00 Watchdog driver by Inprimis Technolgies.
wd1100.c: a few hacks by erich.titl at think.ch
wd1100.c: Can't register device.

Which wd1100 should I use?
http://www.conman.org/software/wd1100/
or
http://www.voyage.hk/download/kernel_patch/2.6/

I've applied the reboot patch from voyage web patch.
Is this no more necessary?

BTW: I don't have a /proc/sys/dev/wd/ directory

rmmod wd1100
Gives the following:
