a better fix might be for whatever sets nvidia as default graphics provider to only do so if the hardware is present, but I don't know whether that's practical.
The package already has a check in http://sources.debian.net/src/nvidia-graphics-drivers/340.46-5/debian/libgl1-nvidia-glx.preinst.in that offers to abort an install/upgrade on hardware that is too old for the new driver version, but it doesn't warn for hardware that isn't Nvidia at all (deliberately, according to the changelog; the warning currently suggests using nvidia-legacy-304xx-driver instead, which is the right solution for old Nvidia hardware but probably as bad as plain nvidia-driver on non-Nvidia hardware).
