True, but the kernels you use now undoubtedly use features of the instruction set that are not available on older systems. Would you like us to eliminate those as well? Where is that line of, "Which subset of the modern IA32 processor instruction set is considered to be good enough?" There is no such thing as "generic x86" support. All of the distributions make assumptions on what hardware they support. All distributions have an arbitrary line. Given the above referenced goals for MeeGo, it made sense to require support for more modern processors. As others have stated, there is nothing precluding anyone from using the MeeGo source code and building it with different options. > >Your position is so strong that this start feeling like Meego is now a >Intel marketing tools.
