I've had my UK passport stamped in Hungary, Germany and Switzerland (not in the EU I realise) on arrival and departure, just had to ask. My German friends have had thiers stamp on request in Germany and in the UK (Edinburgh Airport).
Someone told me I'd have trouble in America with such stamps (I also have stamps from museums in Liechtenstein and Berlin) but no one cared. In fact I've crossed many borders now with such stamps and no one has even raised an eyebrow at them, apart from some German Immigration officers at HAM having a laugh at my Checkpoint Charlie one.
I'd say just ask for them and see what happens. They can only say no, like the man in Dublin did to me when I arrived there from Zurich.
