I want to write some data into the on-board eeprom & have the following 
questions :

1. Can I write to the eeprom by simply opening the file 
"/sys/bus/i2c/devices/0-0050/eeprom" ?
2. Why is this file 32768 bytes in size (I would have expected it to be 
4096 bytes). The contents of the file appears to be 8 contiguous copies of 
the 4K eeprom contents.
3. If the answer to (1) is yes, can I open the file in read/write mode, 
seek to a position near the end and then write some data to it, or do I 
need to write the complete 4K ?
4. Do I need to erase the chip before writing to it ?

I know that I will need to disable the write-protection by grounding TP4.

I'm running ubuntu on a rev C Element14 BBB.

As a matter of interest, I've noticed that the standard eeprom contents on 
an element14 manufactured BBB (Rev C) seems to have the wrong board type 
defined (00A5 instead of 00C0)
