First, let’s talk about Nook Color CM9 build, a lot of hardware components are working right now, but there are still lots of hiccups.
Working: Bluetooth (pairing/file transfer only confirmed), Wi-FI, backlight, accelerometer, Google Apps, Setcpu/overclock, Battery levels/charging, physical menu button, touchscreen, 3D games, screenshots, and USB-mounting
Not-Working: Sound, video, full 2d acceleration and a lot much more.
This build can be downloaded from here along with installation instructions.
Working: Touchscreen, Wi-Fi, Audio
Not-Working: Bluetooth, Landscape Launcher, SD card partition (there is a newer build, which supposedly fixes this issue, but under testing)
Status of other components is still unknown or they are not working.
You can grab the download from here (new build with SD card fix). Instructions: Backup, Do a FACTORY WIPE, Install (all in TWRP).

I kind of doubt they will ever get blue-tooth working on the Kindle Fire, since the device itself doesn’t actually have blue-tooth.
Actually Kindle Fire does have a bluetooth chip in the hardware – Amazon just offers no support for it in its custom Android OS.
