I would think its dust from the ductwork installation, or much worse a mould buildup (staccibotris otra).  It's not particularly bad for adults but can cause fatal pneumonia in infants.  It only grows where there are temperate humid areas in a house (like ac vents after the ac turns off).

Seconded:  Get it checked by a professional immediately.

Is it blowing out like smoke?
Or is it just discoloring the ceiling around the register?
