If the standard Chromium OS didn't work with your notebook you might want to give Lime Chromium a try. Java is now fully supported with Lime. HTML5 & Flash are fully supported also. Chromium Lime adds additional drivers to Chromium including:
Broadcom WiFi – BCM43XX
Ralink WiFi – RT24XX, RT28XX, RT30XX
Realtek WiFi – R8187SE, R8712U, RTL73, RTL8180, RTL8187, RTL8192XX
nVidia GPUs – 6 series and newer
Hexxeh says they will try to add drivers upon request.
