Another day, another attempt. This time, I added the following circuit instead of L11:

And while it does not solve the problem entirely, it significantly reduces the noise down to an acceptable level. There is enough space on the PBP to fit this circuit, but it's still three components for one. Yet, I don't really have any other idea at the moment. Well, apart from messing with the SMPS chip, but I don't feel like risking to fry the entire board when I only have one to play with.
