> There is no GENERIC kernel ;). Unfortunately, on arm, my understanding is that loadable modules are not (yet?) supported. They are surely not being build. Therefore I am not stripping down, I'm trying to find the necessary modules to include in my monolithic freebsd-arm kernel to get this to work. At least yours and others remarks gives me hope my problem can be resolved without patches :)
Loadable modules on arm work, but on some platforms we don't have /boot/loader support, which means on those platforms you can't load them at boot time, but have to fall back to loading them from /etc/rc.d or on demand.
