okay here's another stab in the dark. when you make a function pointer 
and initialize it with an address (0x0000 in the case) is it the data 
i.e. the address stored in the .data section? this would mean that when 
i reprogramming from the bootloader i am overwriting this necessary 
initialization data and so the jump is not going to the right place and 
keeping me in the bootloader.
