How many times have you found the answer right after posting the 
question? This is more than once for me...  Anyway, the solution was to 
go to one of the stacks with the "fat" icon, do Get Info and change the 
Open With... selector to Revolution, and then click the Change All 
button. Even though the icons remained "fat", double-clicking now 
launches my old friend Rev 2.1 under OS X. After restarting, the icons 
resumed their normal appearance. Whew! Hope this saves someone else 
some grief...
