Maybe this is the problem? I have some feeling that it is illegal to load
modules already compiled in the kernel with the loader.
On the running system kldload (or what is responsible for it) detects
that the module is already in the kernel, but loader can't detect this.
Try commenting out these lines while booting kernel with ums/ukbd modules.
