I tracked down a reasonable radio station (South 107) that streams Georgia Tech football games live. The stream even works on my Sprint Palm Centro so I can listen almost anywhere.
Update 11/1: Some links are still working, but nobody seems to be streaming Georgia Tech-Florida State today. Maybe it's a Georgia law that Georgia Tech can't be on the radio on the day of the Florida-Georgia game.
Some Georgia Tech apparel.
If that doesn't work, maybe Live 101.9 FM will.
WREK may carry the game live too, or you might get a 60 minute set of Chinese drums:
