I found it better to do all this in audit mode (sorry if it was mentioned), it will then apply the setting to your default profile (don't forget copy profile in the answer file, like I did first time... )
I also didn't install any drivers at all, got windows to do it, then I have applied one image to the whole school network, all working sweet as a nut Better than having loads of XP images for each machine.
I am going to try MDT next, for next year anyway
