Hi Alex --
You don't say what kernel you are using. There are two WDTs available for the
ep93xx boards from TS: the native ep93xx WDT and the external TS WDT. The
ep93xx WDT was very buggy (at least at one time, it may be fixed), so the 2.4
TS kernel made sure to turn it off. Make sure your kernel has the driver for
the ts72xx-wdt enabled and the ep93xx-wdt disabled.

No, the TS-7800 is a completely different design, CPU, etc., based on Marvel
chip rather than the Cirrus ep9302 like the TS-72xx.

No, just be sure to pick the right WDT, and the enable the driver in the
kernel. See here for more info:
