Hmm, initially you've been telling about an AVRISP mkII.  The Dragon
is quite a different beast.

This is requesting the Dragon to enter SPI mode.

...which it says does not work.

Of course, that's a different matter then...

I've got an old ATtiny22 in a drawer, which announces itself as an
AT90S2343 (both devices were mostly the same anyway).  I tried a
few combinations of programmers:

. Genuine STK500 running v2 firmware: does not work at all, ISP
  startup fails.  Perhaps the same issue as you are seeing with
  the dragon.

. AVRISP mkII: works flawlessly.

. AVRISP mkI (also running v2.x firmware): works flawlessly.

. AVR Dragon: works flawlessly.

. JTAG ICE mkII (in ISP mode): basically works, but apparently has
  issues talking to the device.  The empty EEPROM pattern is read out
  with interspersed junk data.

. Matthias Weißer's USBisp, running his own STK500v2 protocol
  implementation: works flawlessly.
