Update: ChrUbuntu 12.04 now works on Cr-48 and Samsung Series 5!

I'm happy to announce that I finally found the time to get ChrUbuntu 12.04 working on the original Cr-48 and Samsung Series 5. I achieved this by custom compiling 64-bit Chromium OS kernels for both devices. The instructions in the ChrUbuntu 12.04 blog post have been updated to point to the new script. A few things about this new version of the script:

• The script now works on the 1st generation Cr-48 and Samsung Series 5 Chromebooks. A custom 64-bit kernel is used for Ubuntu. Newer Chromebooks will use the official 64-bit Chrome OS kernel found on the device at script execution time.
• I don't have an Acer Chromebook to test with and there's no public overlay to compile for the Acer (ZFB) device. For now, these boards will use the Cr-48 kernel. If an Acer user tries this script, please report your results back here! I'm particular interested to know if the trackpad and audio work properly.
• The script now detects the size of your hard drive and dynamically adjusts the maximum size you can select for the Ubuntu partition. Hardware modders rejoice!

If you're an original Cr-48 or Samsung Series 5 owner and are looking for a way to say thanks, consider upgrading or getting a family member a Samsung Series 5 550 Chromebook or a Samsung Series 3 Chromebox using these links. The price is the same but a portion of the cost goes to support this blog!
