How far away was the subject and how much further was the background? According to the background, P&S f/4 is equivalent to DSLR f/16. Taking your focal length as directly comparable and assuming you were 1' away, I would have a DoF of about 1" and plenty of scope for bokeh if tried my D40 on the same subject at f/16 (using an online DoF calculator). Even stopped down to f/32 the DoF would be only about 2" at that distance (although diffaction would be causing noticeable problems by that point).

You can get similar effects in a portrait IF the subject is close and the background is some distance away but you don't have as much scope - for example, in a full length portrait, the background would need to be much further away to get it blurred.
