One other reason why this isn't done is because X may interfere with it. If we
don't do a full register update, but change the parts that need a change only,
we will see less flickering (no PLL reprogramming), but we will suffer if X
doesn't restore the registers to the exact same values they were before.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
