Mumriken, I've been reading this most interesting thread, and I'm pretty sure you've misunderstood both the original question and the subsequent points made by other posters. I believe the problem here is one of semantics– that is, you seem very focussed on your own definition of the word "loyal".
Zigur,
Boro and
G55 are
clearly 
using it to mean "consciously serving another", whereas by "loyal" you appear to mean "furthering another's ends, deliberately or not". Do you see the difference?
Now, here's a little quiz for you: do you think Saruman was loyal to Morgoth? What about Gollum? Shelob? Wormtongue? Bill Ferny? Lotho Sackville-Baggins? I mean, he would have been quite pleased with all of them, wouldn't he?
