Atmel's document DOC3297 describes using 3V Dataflash devices in 5 volt systems.

I am using AT45DB041 in a 5V system. It is designed to withstand 5V on
inputs...
All works flawlessly...

Despite scouring the datasheet, I cannot find the answer to this
question:
Can you safely apply 5V inputs to Atmel Dataflash devices? (vcc=2.7V)
It quotes the "Absolute Max input voltage" as 6.25V, so presumably it
won't blow up, but will it work?
I'm using a 5V processor and would rather like to not get involved in
lots of level shifting.
