That looks as if you were using the wrong avrdude.conf file.  If you
run avrdude with -v, it will tell you which file it is using.  You can
always specify a particular avrdude.conf using the -C option.  The
ATmega128's device signature has been known to avrdude.conf for quite
a while now, so it's not supposed to be expected as FF FF FF.

I just tried that using the CVS version under FreeBSD:

$ ./avrdude -C avrdude.conf -p m128 -c avrispmkii -P usb -U 
~/src/avr-libc/doc/examples/demo/demo.hex
