I doubt you have Itanium CPU so you don't need IA64 drivers.
To run nvidia installer you have to change its permission so type in console
chmod +x NVIDIA-Linux-x86-1.0-5328.run
If you get a message like installer wont run in X mode type init 3 then repeat command ./NVIDIA-Linux-x86-1.0-5328.run
You have to change XF86Config(-4) file after you install drivers but I assume you already know that
