I just had a thought. The MOM sends Harry letters when he doesn't 
use his wand. In COS- The Hover Charm was used, no wand, but Harry 
received a notice anyway. In POA the ministry had already modified 
Marge's memory by the time Harry stepped off the night bus- they 
knew - but again, Harry didn't use his wand. Which leads me to 
believe that the MOM doesn't know squat about the person/creature 
casting the spells, nor do they know how they're being cast in the 
first place. They just know that magic is being used. 

My theory has flaws, of course, because the Weasley's use magic to 
connect the Dursley's fireplace to the floo network. NO letter on 
that one, but, perhaps Arthur had permission. Don't know. And, that 
pesky patronous charm in OOP, doesn't help my cause either. Harry 
used his wand, and they knew, but did they really know it was Harry, 
or is it like Amelia Bones said at Harry's trial, "That situation 
has always been closely monitored, given...given past events" (OOP 
P. 143)They just use magical radar for Little Whinging? And, if 
something happens, well then it must be Harry doing it. 

Notice, she uses the word 'situation', I think that's a funny way of 
refering to a geographic location. Hmmmmm
