Mac OS X accesses fancy timer registers inside of the mac-io on bootup.
These really should be ticking at the mac-io bus frequency, but I don't see anyone upset when we just make them as fast as we want to.
With this patch on top of my previous patch queue and latest OpenBIOS I am able to boot Mac OS X 10.4 with -M mac99.
