ADT7420 (also ADM1176) - Need More than 4 on the same I2C channel!

The ADT7420 has two address lines to allow us to set the address of the ADT7420 temp sensor.  There is a similar situation with the current/power monitor ADM1176 chip.

Was wondering if there was a different part which would also say 32 (5 address lines) or 62 (6 address lines) to be set.  The documentation also mentions something about factory programming of the address of the ADT7420.

Any help/suggestions for this?
