Glad to hear it was taken care of properly by the dealer. If the oil light didn't come on and no knocking was heard, then very likely no damage was done...
As a quick side note - it is amazing to me how much abuse a modern engine will take and keep on going. I work part time at a national parts chain, and routinely have customers come in asking me to check their oil, as the oil light has been on for some time. I find cars 3-4 quarts low (out of a total capacity of 5-6 qts). We fill them up and off they go with apparently no major harm being done (at least they aren't knocking when they leave....)
