I'm having the same problem. I'm 6'6" and getting back into cycling after a 10 year hiatus. The hybrids I've found so far that come in larger frames are Trek 7.2 and 7.3 FX (the 7.4 and 7.5 don't for some reason??), Cannondale Quick series, and Specialized crosstrail. The hard part is finding a lbs that stocks the bigger size so you can check fit.
