I had to work on this on for a bit.  I've pressed both buttons many times when 
holding the FR in my left hand.  The button orientation doesn't work out as 
well for that when I switch it to my right hand.  That is, until I realized 
turning it over would orient the buttons the same way as if it were in my 
left hand.

So, give this a try.  Hold the FR in your hand with the screen facing away 
from you (ie, you are looking right at the "openmoko" written on the back) 
with your thumb on the AUX button and all 4 fingers basically next to each 
other on the other side (side with the power button).  When I hold it that 
way, my ring finger naturally ends up on the power button.  Then, press and 
hold the AUX button with your thumb and then press the power button for about 
2 seconds.  Then, you should be able to run dfu-util.  Also, I realized I 
could flip my hand over while holding it this way and still see a bit of the 
screen to know when I had held the buttons long enough.

That's the kind of thinking I like to see!  :)  Though, I have no idea how to 
go about doing this.
