It should just work, assuming that LINUX_MODULE_DIRECTORY is set to
/run/booted-system/kernel/lib/modules and that you are using 'modprobe'
from Guix.  We set LINUX_MODULE_DIRECTORY in /etc/profile on GuixSD.

For insmod, use /run/booted-system/kernel/lib/modules.

It works for me.  Can you try the following command:

  sudo bash -c "echo $LINUX_MODULE_DIRECTORY"

and verify that it prints "/run/booted-system/kernel/lib/modules"?
