The hardware sync of the timebase on SMP G5s uses a black magic
incantation to the i2c clock chip that was inspired from what Darwin
does.
However, this was an earlier version of Darwin that was ... buggy !
heh. This causes the latest models to break though when starting SMP,
so it's worth fixing.
Here's a new version of the incantation based on careful transcription
of the said incantations as found in the latest version of apple's
temple.
