Narrative:

Lga VOR and DME were NOTAM'ed out of service; as noted on the ATIS which we did not notice. Takeoff clearance was the whitestone climb off of runway 31. This requires a turn to 40 degrees at 2.5 miles off the lga DME. No other DME is listed on the SID to make the turn. After noticing no DME readings from lga; we made the turn based on prior experience in the good VFR weather ('wagged it'); with no problem; conflict; nor complaint from ATC. After this we noticed the NOTAM (and had already asked departure about it); and realized we (and many others!) had been given a departure SID that was impossible to follow. As SOP at lga; I had read back the whitestone climb clearance to clearance delivery; and they had confirmed it. Lga clearance delivery failed to stop using the whitestone climb once the lga DME was NOTAM'ed out of service; and came up with an alternate clearance instead; that in fact could be flown. If I had read the whole ATIS; I would have been alerted to question clearance delivery on the validity of our pre departure clearance clearance.
