Jan, For the Arduino Uno we have been using the following command string successfully:
avrdude -p m328p -c avrispmkII -P usb -U efuse:w:0xFF:m -U hfuse:w:0xD9:m -U lfuse:w:0xFF:m -U flash:w:uno.hex:i -U eeprom:w:uno.eep.hex:i Thus argument for efuse is set to FF instead of 05. The short explanation for this is a change inplemented in newer versions of AVRDude (something to do with how AVRDude reads back unused bits). I had the same problem when I started with AMForth and it cost me a lot of time...
