In response to criticism from Linux enthusiasts, Asus has made additional source code archives available for download with code for the asus_acpi module, BusyBox, and several other components. The code released by Asus brings the company into compliance with its obligations under the GPL and should satisfy most of the critics.
The source code changes made by Asus are important because the availability of that code will simplify the process of making other Linux distributions perform better on the Eee PC.
