Unfortunately this doesn't help, you should be able to reproduce it
yourself without access to the actual hardware though.

I worked around this by adding the iicbus dependency to ig4_pci.c (and
also to "files").

Now loading ig4 works and both lynx point controllers are detected.
Loading isl doesn't create any output and doesn't seem to detect any
devices. Also, devinfo shows both controllers (ig4iic0, ig4iic1), but
no iicbus devices.

# devinfo | grep iic
ig4iic0
ig4iic1

-m
