I have the same buzz problem on my laptop...
i wouldn't physically cut the prong, but I have used one of those
little 2-prong to 3-prong adapters - common in the US, you can find them
in any hardware store here, i assume there's an equivalent elsewhere.
You probably know the type - about 1 inch square, it's got a standard US 
3-prong outlet on one side and a 2-prong plug on the other, 
with a little tab that you're meant to screw into the center screw of 
the wall outlet.
If you ensure that the tab doesn't contact anything grounded, 
voila, ground is broken.

is this a safety hazard?  I'm not really sure.
Be careful.

A better option would be an AC isolation transformer, but those
don't seem to be easy to find in a packaged, ready-to-use form.
