I have indeed missed this point in Marc's reply -- and you are right, 
the single column case is the only one where it is common that one does 
not care for multiple mapping. So, sorry for the noise.

How comes I never knew 'mapIds' even though it is clearly mentioned in 
the AnnotationDb help page? Maybe the page is too long, or --more 
likely-- I'm to impatient when browsing through help pages.
