It sounds like you are trying to install the x86_64 version of binutils, which is probably not what you want. The x86_64 is for the new 64-bit processors.
You probably need the package with _i686 or _i386, etc.
I don't use Mandrake myself, but it's highly unusual for a distro not to install binutils as a standard package. Are you sure it's not there?
Try running "which ld" to see if it finds it, or even "locate ld" if it is not in your path. If locate finds it, you just need to adjust your path and recompile the drivers.
