Linux, which has long been cross-platform, should have a long head start in this niche, right? Well, blogger Brian Proffitt explains just how messy the state of Linux support for ARM is right now, partially as a result of mutually conflicting kernel hacks from ARM manufacturers who just wanted to get their products out the door and weren't necessarily abiding by the GPL obligations to release code. Things are imporving now, not least because Linus is taking a personal hand in things, but sorting the mess out will take time."
