Not for the couple I've seen running @851, but I don't have a great deal of experience there so I can't say definitively. Again, if that happens you can just flash back to 451 firmware.

I'll try to write a step by step for this tomorrow, basically there is a program that will modify the factory upgrade.exe files so they will allow 851 software to load into a 451. There are also binary files around to use with other tools.
