Need video and SM bus controller driver for xp pro for laptop model L455D-S5976

An employee bought this Toshiba laptop here for a school unbeknownst to me, as a replacement for a stolen machine.  It came w/ win 7 which I'm not administering yet, so I wiped it out and put on win xp pro.  Got all drivers except video and SM Bus controller.  A company that supposedly services support for Toshiba said they guarantee they'd find me a driver if I paid them $170 software support.  So the drivers supposedly exist.  Toshiba's site is of no help; only gives drivers for win 7 and they don't work.  Any ideas of where to go?  Laptop is a Satellite Model L455D-S5976
