I've got interesting results (in the bad sense of the phrase): I do get
the message "Invalid time in real time clock. Check and reset the time
immediately" (the i386 message) BUT my time gets reset to 0 (midnight
1970.)

I see your patch and it shouldn't do that. Could it be a compiler bug,
so the effects change after trivial code has been changed?
