You're entirely right, but Wondermedia/VIA actually have a moderately good history with their GPL source for ARM system-on-a-chips. Although most end vendors of devices using the WM8xxx line of chips are GPL violators (direct-from-China business models where noone cares), Wondermedia themselves have been supplying GPL source via Harald Welte of Gpl-Violations (formerly also employed by VIA): http://ftp.gpl-devices.org/pub/vendors/Wondermedia/ http://ftp.gpl-devices.org/pub/vendors/Wondermedia/ 100% blob-free to my knowledge. Unfortunately they haven't released anything for the WM87xx series (apc.io) yet, but these devices are brand new so here's hoping. If you're interested you can dig up some more details, and the follow from-scratch open kernel development efforts, at http://groups.google.com/group/vt8500-wm8505-linux-kernel/ http://groups.google.com/group/vt8500-wm8505-linux-kernel/ (What I -really- hope they release is publicly available datasheets.)
