--- Comment #2 from Pierre-Alain TORET <pierre-alain+freebsd@toret.fr> ---
I'm having the same issue on a Dell Chromebook 13 - 7310 (namecode LULU it
seems). It also has been flashed with a Coreboot distribution (mrchromebox'=
s).

dmesg reports the following :
driver bug: Unable to set devclass (class: ppc devname: (unknown))
driver bug: Unable to set devclass (class: ppc devname: (unknown))
ig4iic0: <Designware I2C Controller> iomem 0x91122000-0x91122fff irq 7 on a=
cpi0
ig4iic0: controller error during attach-1
device_attach: ig4iic0 attach returned 6

cpi0
ig4iic0: controller error during attach-1
device_attach: ig4iic0 attach returned 6

As Mark reported, in my case the keyboard also works fine. Only no touchpad.
