Google has announced Chromium OS for a long time(2009/11/19), and I tried to build the image from source code. The building script can generate vmware image and write image into bootable USB disk. But the default image can't let my Thinkpad R51 wifi work. Looking into the kernel boot log, it fails at the loading stage when it wants to load ipw2200 firmware binary file.
The simple way to solve this issue is to copy the needed file from Ubuntu 9.10.
Copy the /lib/firmware/ipw2200-bss.fw to USBDisk:/C-ROOT/lib/firmware/2.6.31.4-chromeos-intel-menlow/ipw2200-bss.fw

PS: After change the default kernel config, and rebuild image, the sound on Thinkpad R51 works fine.
