 possibly there is a way to do this in OpenFirmware.  I don't know
 what's wrong with your RTC in particular.  How do you know it's
 corrupt?  Did you see an error message?
 This is for older Suns, but you could try parts of it:
 I don't think it's a good idea to add architecture-specific user
 dialog to the bootup process.  Whatever you want the kernel to
 do---ignore the problem, work around the problem, fix the problem, do
 nothing differently but print a better error message---it should
 always do that thing, not ask questions.
