I guess we should not fail, like in case the module is not compiled
for the current kernel, all should work just fine. In many cases
"depends" will be used to make sure that the module listed as a
dependency will work correctly, and not that the loaded module would
fail if the dependency is not resolved.

Sounds good.

Hmm, since we don't really "depend" on another module in most cases,
we might want something like "softdepend", prerequire", "preload"?.
