The evdev_drv.so module is present in the image, but e.g., lsmod | grep evdev does not produce any output (modprobe evdev reports fatal error: cannot load module). Is the evdev support missing from the kernel of some reason, and can it be fixed easily somehow?

EVDEV is typically built into our images, not as a module. If you
zcat /proc/config.gz, and grep for EVDEV, what do you see ?

I have created a custom bitbake recipe already, inheriting from core-image-sato, which adds a few packages. Can removal of packages be easily specified in the custom recipe as well?
