Archos hacker Bubu just released the multi-boot menu support for the Archos Gen8 Tablets, it reportedly works great on Archos 70 Internet Tablet and Archos 101 Internet Tablet, find the release here: http://www.openaos.org/archives/739
This is how this is cool, you can install the official alternative OS firmware from Archos called the Special Developer Edition firmware here: http://www.archos.com/support/support_tech/_ppp.html?country=us&lang=en&p=gen8
Then you can install alternative firmwares and have them right there available in your multi-boot menu on your Archos, so you could for example today choose between Archos official Android firmware, Debian Linux and Angstrom Linux.
If more software hackers contribute, Archos tablets may also run Ubuntu 11.4, Chromium OS, Gingerbread and any other embedded Linux OS through this multi-boot system.
Bubu and the team at OpenAOS.org previously released this solution for the Archos Gen6 and Gen7 tablets as well.
