Change bit 0 of the ATmega169 efuse 'write' opcode from 'x' (ignore) 

to 'i' (input).  Even though this bit should be ignored, it should not
be changed.  The 'x' setting sets the bit to zero which programs it
and could cause undefined behaviour.  Setting to 'i' enables it to be
rewritten to its old value.

A better solution might be to read the fuse byte, apply the new value
while leaving the 'x' bit alone, then writing the value back.  The
current fix is a workaround which allows the developer to change the
bit.
