In rc.conf I have

kld_list="ig4 iichid amdgpu"

Replace amdgpu with radeonkms. It will in turn load various
radeon*_bin.ko modules for firmware. I don't have this
card so this is just a guess (I am running 13.0-ALPHA3).
Compile /usr/ports/graphics/drm-fbsd13-kmod at the same
time as the kernel by adding

PORTS_MODULES=graphics/drm-fbsd13-kmod
PORTS_MODULES+=graphics/gpu-firmware-kmod

to /etc/src.conf. AFAIK installing a package won't work.

I need ig4 and iichid drivers for the touchpad.
