If you read the messages, you will find out that the problem is that no
RTC driver is registered with the MI todr code.  It is likely that this
could be solved by adding an RTC driver which just uses the boot-info time.

Alternatively, for a port which gets the time passed in bootinfo, I can
see a case being made for #ifdef'ing out the warning messages in
kern_todr.c.   Please not that this case is very different from assuming
an NFS root mount is current -- one is probably a good assumption, while
the other might not be.
