This is the invocation I use from Mac OS X:
avrdude -c dragon_isp -p t85 -B 100 -P usb -U flash:w:main.hex:i

That's an ISP clock of 1 MHz. If your ATtiny44 is still virgin, it
has a CPU clock of 1 MHz, so the maximal allowed ISP clock is less
than 250 kHz. Try running with -B 10 instead.
Bummer. Neither that, nor adding information to udev/rules.d seems
to help. :(
Well, the udev rules won't help get your ATtiny to talk to the
Dragon. The udev rules only allow you to run avrdude as a user, so
you don't have to sudo or otherwise be root to talk to the Dragon.
