Non-power V schools that have hosted Gameday (tOSU has hosted the most -- 17):
Air Force (3)
James Madison (2)
North Dakota State (2)
Army
Harvard
Boise State
Bowling Green (this shocks me)
Florida A&M
Houston
Temple
Penn
Western Michigan
Williams
FWIW, Gameday has been held at the Army/Navy game three times, but the games are always on a neutral field. Gameday has visited Army and Air Force, but never Navy.
Finally, Cal, Kansas, Cuse and Illinois have all been the road team for Gameday appearances. So, the 7 schools Power V schools that have never had Gameday appear for a home or a road game are:
Iowa State
Minnesota
Maryland
Duke
UVA
Wake
Rutgers
If you add in college hoop Gameday (which began in 2005), all of the schools left out of college football Gameday have hosted college hoop Gameday except:
Minnesota
Rutgers AND
yes, Wake Forest.
Ouch.
