I think you'd probably just use crouton instead in which case you'll get flawless hardware support since it's using Chrome OS's kernel & drivers.
It's pretty great (I don't have one, but I have heard universal positivity for it) That said, you loose a lot of the security features that come with a Chromebook when you enable Dev mode.
Does it still take one wrong key press at the wrong time during boot to delete all local files when in dev mode?
GalliumOS is beautiful, period... great hardware support
