We have some machines that load rtc and others that load genrtc....we have
not found a good answer as to why (since they are the SAME hardware) or
a quick answer on how to force rtc over genrtc.

I'll post something if I find a good answer. For now it's unload the genrtc
and load rtc manually....then ztdummy is happy and so is meetme.
