Yeah it would seem that there is some disaggrement on the matter. The manufacturers aren't that genereous with information, so it would seem you are right in most instances. I'm quite sure I got one on my 8800 gts and it sounds nothing like a mb beep.
I have mate that confirmed he got one I think on a card as old as the 7800.

Hmmm, interesting data! So, what we have so far is that the sound isn't made by a capacitor or VRM that's about to blow, but by a part that was designed to buzz, presumably when power is "perceived" by it as being too low. I'm guessing it's supposed to sound a loud alarm when the power is obviously off, like if one of the 6-pin adaptors is disconnected, but it can sort of "start" to activate (buzz) if power is borderline.

emailed nvidia and the rep said the cards have an "Insufficient power" buzzer. That they have had it for years. (I never noticed it or ever heard it).
