Major thanks to Sparkym3 for coming up with this exploit, and to Justin Case & Hashcode for helping do this on my tablet today.
Here are the files that you need:

http://www.reverendkyle.com/download/Kindle_Fire_HD_ADB_Drivers.zip
Be sure to install ADB on your computer first!

The commands:
adb shell
rm -r /data/local/tmp
ln -s /data/ /data/local/tmp

exit
abd reboot
adb shell mount -o remount,rw /system

I demonstrate the HDMI output capabilities of the Amazon Kindle Fire HD 7" Tablet. I am very impressed with this feature.
PLEASE NOTE: This video does not do the output justice. Trust me, the color is very accurate and the contrast and saturation are very close to what you see on the tablet's screen. Unfortunately, this video shows the TV as being a little blown out. This is not the case in real life.
Stay tuned for even more videos soon!
