It would be cool, if we will be able to read (from kernel) modmetadata
before module is loaded. I think this is what is stopping as to check
if module with the same name already exists.

I may be wrong, while I haven't spend enough time on this yet.
If we are able to get only modmetadata from .ko from inside the kernel
(before loading module), tell me how, so we can fix this long-standing
KLD issue.
