Is there something harm that a mortal user could do using direct
access to i2c bus ?  If so, consider checking for root privs.
This seems to much of low level access to allow to everybody.

chmod'ing the device may not be an option.  I would not want
every bt848 program to be suid either.  And depending on the
power of i2c (think hardware debug), fbtab is not an option
also.
