After a quick look in some other ppc manuals (AMCC and Freescale) this seems 
to be not only a 440GX problem, but a generic ppc problem. I will prepare a 
patch for this.

I didn't find any code referencing these registers. Do you have an 
command/application using these timebase regsisters, which could be 
interesting for the community? If so, please share it it with us.

And please submit a proper patch next time (CHANGELOG, etc...)

Best regards,
Stefan
