Notion Ink has released the Android 4.0.3 Alpha ROM for the Adam tablet. They teased ICS on the Adam last month. They have fixed most of the bugs such as Audio, Sensors, Bluetooth, Wi-Fi, SD Card Mount, GPS and it also has Hardware Acceleration in this Alpha version.
Still there are some bugs that need to be fixed such as 3G, Camera, USB Flash Drive, Video Acceleration for High Quality YouTube Video and more. Since this is just the alpha version these bugs would be fixed eventually in upcoming releases.
Here’s a video walk-though of the Adam running on ICS
