Says: ========= Some hardware manufacturers simply won't tell us how to write drivers for their hardware. Others won't allow us access to the documentation without a non-disclosure agreement that would prevent us from releasing the Linux source code. One example is the IBM laptop DSP sound system used in recent ThinkPad systems ? some of these systems also couple the sound system to the modem.
IBM released mwave GPL drivers and info a long time back now, and its in the base kernel. Pick a newer evil example - say Nvidia ?
