Habits die hard, I guess -- putting something on a stable branch when it
has only been tested by myself is something I am not accustomed to
doing.  If Jonas (or any other person) can confirm that it at least
boots and doesn't trash the SD card, I'll immediately send in a formal
version of that patch (properly style-checked and all).

One question, as I review this code myself -- I put a spinlock to
protect the enable/disable of the clocks, but I'm not sure that has
turned out to be necessary.  The register in question is never touched
inside the IRQ handler, so I think it is unnecessary.  If someone can
confirm that it's safe to remove that spinlock, I'll clean that bit out.
