nvidia-xconfig is an X configuration utility that generates a configuration file specifically for the proprietary non-free NVIDIA X drivers. Since upstream only releases these drivers for i386 and amd64, it's pointless to build this package on any other architecture. Could you please remove the old ia64 build of this package from testing?
