You should make sure that USE_RTC is defined, and then you WON'T depend
on the value of HZ in the kernel, because the interrupts will be generated
by the RTC chip and not hooked into the kernel jiffy clock.

You only need to use ztdummy if you have NO zaptel hardware in the system.
Once you install a TE210P, you should remove ztdummy and make sure it does
not get loaded.

Hope this helps!
