First of all I have to thank the CM people, especially mbm, nemith, fattire and cvpcs for their work on gingerbread which helped me a lot in understanding where to look and what to patch.
The whole thing is based on the honeycomb preview emulator images, some of the B&N modules+driver, pieces from the upcoming CM7 and manual patching ARM assembler in libraries, writing ugly scripts to hack around various issues, a lot of time and many brain cells.
Use this on your own risk. I'm not responsible for any damages. This is not meant as a primetime ready rom. This is a preview after all.
The unzipped image is around 3.5gb and fits on 4GB SD cards.
increased touchscreen sensitivity and made touchscreen more usable close to the borders (kernel change)
fixed heap size issue to get much more programs running (e.g. nook app, kindle app, etc.)
v03 - 02/05/2011

sd card access and secure storage support
turned off the debug screen flashes and vibrator
added display timings
sd card image now usable on 4gb cards
changed to a self compiled kernel to make these things work
reduced compressed image size

v01 - 02/01/2011
initial release
Status
What works:
Graphics acceleration
Accelerometer
Wireless!
Touchscreen
Buttons
Sleep/Wakeup
Sound
Known issues:
The accelerometer behaves funky. Will try to fix this.
The Gallery app crashes when opening an image. Not my fault, it's broken in the emulator from google too.
Doesn't work:
DSP e.g. no hardware video decoding (and will possibly never work before the AOSP release)
FAQ
Q: Why?
A: I thought it would be fun. It was and still is. And now developers have an actual device to test their apps on instead of relying on the slow emulator.
Q: How?
A: I'm planning to write a blog post. Mostly learning how Android works, debugging, patching, reusing binaries from different sources, finding easy ways to reach a goal, try and error, a lot of brain power.
Q: During boot I get stuck at the Android screen with the blinking cursor.
A: It seems to be a timing issue with mounting the partitions. Sometimes rebooting helps to get it booting. If not a different SD card might to the trick.
Q: Why is there no Market app installed?
A: There's no legal way to distribute the google apps with a ROM.
Q: Angry Birds, Nook reader, Kindle app?
A: Yes.
Q: I want to port Honeycomb to device xyz... send me the instructions how to do that now!
A: I like the 'I' in that sentence - but there are no instructions, no source, no nothing. Learn and read about Android, Android porting, making custom roms, embedded systems, ARM assembly, driver programming, programming in general, the Linux Kernel and much more - and when you're comfortable and have experience with all of that come back and do your port.
Q: Can you port Honeycomb to device xyz?
A: I don't have xyz. And even if device xyz would magically appear at my front door doesn't necessarily mean I'll have the time and motivation to port anything to it.
Amazing work. I'm always impressed when people get an SDK image booting on a device and working properly, but this isn't even technically a tablet! It's an e-reader that was hacked. Unreal.
I decided to release what I have so far. May everybody have some fun with it.

-DSP e.g. no hardware video decoding

The unzipped image is around 4gb. I use it on a 8gb sd-card. In principle the image should work on a 4gb card.
I'm going to buy an 8GB card on payday. My 2GB isn't enough for this, but that's amazing. Will definitely be using a lot. Thanks a ton for all of your hard work! Expect donations.
Here are some basic instructions on how to flash it:
Windows Instructions
Download Win32DiskImager.exe
Download the file in the first post and extract the img from the zip

Click the Folder icon and locate the img file you extracted earlier
Click on Write and then wait...
Once its done remove the SD card from your computer
Power off your nook color and insert the MicroSD you just prepared
