Btw, didn't mfleming want to try using capsules for other funky stuff
like early logging and pstore-like logging in panic time so that we can
read out crash data on the next boot?
Which would mean that capsules would need a completely different
interface, something new for shuffling lotsa binary data in and out of
the kernel and in and out of the UEFI...
Which would make the firmware_class thing completely inappropriate for
that.
Hmmm?
