I am using my AVR Dragon to program the Arduino I built. In AVR Studio I have on my ATmega168 0x1E 0x94 0x06 (8.0 MHz Oscillator Calibration byte 0x8C) @ 3.3 volts. I have my Arduino board powered by a battery pack 3xAAA and then an LM2937 3.3Volts.
I programmed the ATmegaBOOT_168_diecimila.hex, And I compared the flash with a bought Arduino and it has a voltage of 5.0 volts | Sure I can always change or re-write my bootloader and I can program the AVR directly in a variety of ways with the STK-500 and AVR Dragon It should be noted that you have to modify your dragon yourself ( 1x40 zif, 3 @ 2-row-20 male headers, and the headers should be 1@20, 1@10, 2@3, 1@5. ***So correspondingly you have a 40,20, 2@6,10***) Solder the headers in and solder the 40 pin zif in, their should be no electrical connection between the small headers - that get the signal from the dragon - and the 40 pin header for the zif, here is where you use female jumpers to Vcc, GND and programming JTAG, ISP, or HV_PROG.

AVR Dragon
I put some pictures of my Dragon on my home site. http://users.adelphia.net/~quispqix/
And I show how I followed the directions on the AVR Studio 4 users guide to do the necessary
hacks to the Dragon. I also try to explain SPI or ISP programming. Now if I can only learn C++
If anyone reads my blog please e-mail me = quispqix@gmail.com thx's
