Just as RUTS warned us, the new cost of parking passes bought the day of a Penn State game is going up this fall. After being $20 last year (weren't they $10 just a few years ago? I remember when the were $5) buying them on gameday will set you back $40.
There is a solution though and it will make your life a lot easier if you do it -- buy them in advance for a more reasonable $12 (including service charge). You can apparently get them via the PSU Athletics Ticket Office at (800) NITTANY or e-mail firstname.lastname@example.org. You can also just get them on Ticketmaster, so I assembled direct links to parking passes for each Penn State home game.
Single game tickets also appear to be available.
