I used to slip the 727 on final(wing down method) in a crosswind as allowed by the AFM. Works well up to a certain crosswind amount depending on the weight, as given in our manuals. Then a crab(or combination) is required. 737 was slipped as well.
As for the big sideslips like you might have done in a light aircraft in order to lose height on final approach, I have only heard of a 767 doing that once. This was an emergency in Gimli, Canada where it had run out of fuel in 1982 and was landing on a relatively short runway. Apparantly a very large sideslip was done on short final(whichworked) in order to land near the beginning of the runway.
