Run this in Bootcamp!
If you run the updater in a VM, it may leave out some driver updates. In my case, the ATI X1600 driver didn't get updated until I re-ran in Bootcamp.
Also, at least in my case, SP3 installed over SP2 & Leopard Bootcamp drivers fine (in VM) and booted fine in Bootcamp before these driver updates were installed. YMMV.
