I posted this is in the regular Kindle forums earlier, but thought it was prudent to add here as well. I order for version 0.2 to work on the Kindle DX, you need to add the following in bold:

if serial.startswith("B001"):
print "Kindle 1 serial number detected"
elif serial.startswith("B002"):
print "Kindle 2 serial number detected"
elif serial.startswith("B004"):
print "Kindle DX serial number detected"
else:
print "Warning: unrecognized serial number. Please recheck input."
sys.exit(1)

Someone should consider taking over the code and releasing an official 0.3 version.

I might add that my wife got a replacement Kindle 1 with a S/N beginning B101 so I I had to modify the script for that.

Wow, thanks Condor!
