Quick and dirty fix for these problems:

Get a square wave of any freq.(up to the max of the chip) (I use 2MHz as 
that is the fastest my signal gen will do)

use a scope probe on X1 inject the signal into the X1 input of the AVR, 
hold the probe on the pin while  you let the programmer reprogram the 
fuses correctly :)

I have rescued batches of M128's when a customer set them ALL WRONG !!!
