Right. Here's the complete diff. I've also fixed the typo you told me.

Can you send me your device-tree dump? If it's really a MPC7447A (not a
MPC7447) then the processor has the HID1 register and supports DFS2. So

There is no reason for this variable to be global. You should put it in
your device' softc instead.
Ok, new diff below.

Reading the doc again, it's said that the time base register is clocked

You can check if your machine supports it by looking for the
cpu-vcore-select node in your openfirmware dump:
$ eeprom -p |grep vcore
FWIW, the only known (to us) systems with that node are:
PowerBook4,3
PowerBook6,5
PowerBook6,7
PowerBook6,8

We typically use pure lower case for stuff that shows up in dmesg.
And I'm not sure the Dynamic Frequency Switching part really adds
useful information. Perhaps just change this in:
