 Indeed, many of the packages, including Debian-particular packages (such as Iceweasel and Icedove) ported to gNewSense are simply modified in such a way that they no longer provide such courtesy access to non-free software options.Since gNewSense's repositories contain only free software, support for hardware which requires firmware and for which no free firmware exists (such as some wireless network cards) is not available.By May 1, 2008, 3D graphics and application support had also been removed because of licensing issues with Mesa 3D.
