@hwhw how did you found that holding volume down brings Kindle 3 in usb loader mode?
To be sure that everything works, I tested K3G which works.

I discovered the K3 "magic key" by rebooting while holding EACH button, until I found one that enumerated as a "different" USB device. As I recall, I almost gave up before finally realizing that the volume buttons might work, so they were literally the last thing I tried.
I tried both the DX and DXG too, but I did not find it. I think I gave up before trying ALL buttons on both devices, but I tried the obvious ones at least.
I later learned that headphone insertion and removal generate keycodes too (as far as "waitforkey" is concerned), but it seems odd that rebooting with headphones in should boot to USB Downloader mode... It is worth a try though, if somebody wants to try it... Or try all the letter keys?
EDIT: You can speed up the process by leaving the USB cable connected so the power LED is on, then hold the power button (backed off just enough to see the LED at its edge) until the LED turns off, then press the "potential magic key", then release power, then release the tested magic key. Look for a new USB VID/PID detected at the host PC.
EDIT2: It is possible (but unlikely) that we need a combination of keys. It is also possible that the DX or DXG uses an internal connection or jumper to boot to USB Downloader mode, instead of a magic key.
