I should think. If I saw a cv like yours, right or wrong.
It would make suspicious of
your ability (left before got found out)
attention span (got bored)
any claim whatsoever of loyalty. (liar)
Now personally I don't have a problem with you not being loyal to an employer, as long as you don't make the claim that you are. Employers do tend to view that one from their side big time though. In fact you usually find the ones most concerned about your loyalty as the ones who will do you up the back any time it's convenient, having absolutely none of their own.
The question to me, would be do I think I'm offering you an opportunity that would be valuable enough to you, to stick it out. If you couldn't convince me that I was, you wouldn't get a sniff. Sticking with me just to make your cv look better would not be a way to convince me by the way.
Personally I'd look at contracting if I was you, where this sort of thing wouldn't matter. When you do get a job stick it out for two years unless it turns out to seriously damage your future prospects.
My first employer last 19 years by the way, though I did do six jobs over that time, they thought I was showing disloyalty when I left.
Seeing as your case for making any claim to being loyal is quite (very very) weak, turn it on it's head. Ask them why you should be loyal. What's their retention policy like, how successful is it etc.
In other words show interest in being loyal, but state very clearly that loyalty is a two way street.
