I installed Gallium several years back, on a chromebook that didn't support any of that (at the time, at least). Gallium was also the only distro I found that worked out of the box with full hardware support (audio, webcam, etc).
Other commenters say that those drivers are now in other distros too, so Gallium may no longer have its original USPs...
Running other OSs on my chromebook is a bit of a pain, because every time you boot, you get a BIOS screen warning you about non-google software (and offering to wipe everything!). Also, (and maybe unique to my chromebook model), it has a nasty gotcha: if you ever let the battery drain empty, then the firmware loses its settings and it will no longer boot at all :( That one was fun to diagnose and fix...
