I had a damaged motherboard that gave that error (the Pc had been dropped in 
transit).

Also, I recall that having the HPET timer enabled in th BIOS and/or the kernel 
may give this error. If the 'HPET timer supplies IRQ' is enabled in the 
kernel then rtc.ko is just a stub i.e. there is no actual code running. This 
will only be a problem if you are running just ztdummy.
