Yes, I do own the MSAR, and BTW it costs $25. In the latest edition (2009-10), the MCAT data shows the range from the 10th to 90th percentile for each school, rather than the absolute range of scores accepted. Using that data, there are 34 schools that have a 10th percentile at or below 7 for any section of the MCAT. None of these are in New York (state or city), 20 are state schools which admit very few or no OOS students, 3 are HBS, and 4 are on Puerto Rico (requires Spanish fluency). So that leaves a grand total of 7 schools which accept meaningful numbers of students from all states with 7's. (If a given school has accepted scores below 7, but the 10th percentile is at 7 or higher, that suggests that a very small number of students are involved, most likely URMs or very exceptional circumstances.)
Naturally, I applied to all 7, as well as 20 others where the MCAT ranges were higher than mine. I just got my first acceptance, but it was at one of the schools on record as taking students with 7's. I may get into one or two others (I'm on 3 waitlists, and have 2 decisions coming up), but all of those schools have MCAT ranges that go down to 7 or 8.
That doesn't suggest that students with 7's have great odds of getting into highly competitive schools. In fact, as KeyzerSoze noted in his post, AMCAS data on p. 25 of the MSAR shows that about 80% of students with 7's are not accepted to ANY med school.
My motto is: go for your dreams but know what you're up against, and be prepared.
