Where should kernel space headers for building depending kernel
modules go? You need the "i2c-kernheaders" at least for building the
lm_sensors kernel modules. Perhaps /usr/include/linux is for userland
interfacing the kernel, but then there is no FHS place for
kernel-kernel headers (they are assumed to be hiding in the kernel
source only). Perhaps per kernel /lib/modules/.../{source,build}
locations would have been more appropriate.

Yes, sorry, a typo. :)
