Markus,
Thanks for sharing your findings. I had no idea avrdude supported
debugwire in this way.

Thanks Jörg,
this works reasonably well with avrdude now. Along these steps:
1) Program DWEN with avrdude
Example: avrdude -P usb -c dragon_isp -p t85 -v -U hfuse:w:0x9D:m
2) Perform actions using debugwire
Example: avrdude -P usb -c dragon_dw -p t85 -v -U flash:w:sample.hex
1) UnProgram DWEN with avrdude
Example: avrdude -P usb -c dragon_isp -p t85 -v -U hfuse:w:0xDD:m
There are some instabilities around, for example avrdude would segfault
after step 1). It looks they are dragon related, power-cycling the dragon
did got me unstuck when stuck.
