I have a problem that the clock is being reset to 1970 most of the times
I do "shutdown -h now" on my PowerBook (Google tells me that I'm not
alone -- even OS X had this problem in 10.2.4).

Some debugging shows that the clock is reset when calling OF_exit().
Changing the function ppc_exit() to just say "while(1);" (and then
turn of the computer using the power switch) gives me a correct
time when booting the next time.

Any ideas how to fix this?
