Chromium maybe. I'm not sure there are any Chromebooks based on ARM yet although there seems to be a profile for building tegra2 devices. I know the Trimslice is supposed to be able to run it but I haven't actually seen a software release of Google Chrome for it. Hexxeh does seem to be working on it for the Pi but I haven't used the Pi so I can't say (I personally need a little more power than armv6 has)
