If Nintendo sets up decent security for the system it shouldn't be possible. But if we look at Nintendo's track record for security it is not that good.
I'm sure there's probably some check that the system would do while in bark mode to see if it is a legitimate system menu. Then again looking at the Wii can't say it matters what system menu you're on if the 3DS uses something similar to IOSes. Hopefully Nintendo has learned from the large security holes they left with the Wii.
Nintendo may claim that the 3DS will be unhackable, but only time will tell. I say the only way we'll know is when someone has the 3DS in their hands.
