Yes it was the same problem, actually, as thor and others told me over at the Dahon forums. It's sorted now. I was somehow misguided by what I read in the manual and thought it had to do with the handlepost headset. Still, I'm beginning to think that folding bikes require more maintenance and regular minor adjustments than I thought. Or maybe it's just Dahon ones, I don't know.

It's on page 42 of the manual (page number may be different in yours, as my manual has the Spanish version first). The section is called "Headset adjustment instructions", and it is specifically mentioned as a solution for the handlebar not being perpendicular to the front wheel, which was my exact problem. That's why I got confused.
Thanks everyone for your input and advice.
