Are there any uptodate Chromium OS binaries available? I only found chromeos.hexxeh.net, but the packages are quite old.
The latest x86 image can be found here http://arnoldthebat.co.uk/wordpress/
If you want stable binary, you may use "canal build". http://www.canal.mokuren.ne.jp/ChromiumOS/usb.html But this kernel version is old.
