The Giants vs. Patriots match-up averaged an approximate 89.10 million viewers and a 34.8 rating/67 share among adults 18-49 from 7-10 p.m. (the 6:20-7 p.m. portion of the game was not available, which means that these results will increase)

The Super Bowl Post Game at 10 p.m. scored an estimated 68.32 million viewers and a 28.2/57 among adults 18-49, while the first-half of a Sunday edition of House netted 32.78 million viewers and a 14.4/34 in the demo at 10:30 p.m.
Those numbers could change a bit as
House didn't start right on the half-hour mark, and I don't know whether this includes NY & Boston.
eta: it'll be interesting to see if Nielsen is able to figure out DVR viewing for the episode. Assuming people actually managed to record enough of it to watch :P
eta 2: Fast national numbers from
Futon Critic:
prime time portion of
House: households: 17.5/30, A18-49: 14.4
for comparison, last year's post-Super Bowl
Criminal Minds had households 14.7/25, A18-49: 10.0, which was -23.44% households and -33.33% A18-49 from the previous year's post-Super Bowl
Grey's Anatomy. Which I guess puts
House at a little less than
GA in households and a little more than
GA in A18-49. Depending on how the percentages were calculated and how the viewers/rating point compare...
another comparison, the best previous fast national ratings for
House were 30 Jan 2007 (ep. 312): households 15.9/24, A18-49 11.2, which translated into 27.34M total viewers in the final numbers for the week. The average for eps 401-410 is roughly households 10.7/16, A18-49 7.4/18 (18.07M viewers).
I still have no idea how Nielsen accounts for differing amounts of
House falling into the prime time hours and 2 big markets not having any PT
House...
