How to undo bad graphics driver update

[pokeefe0001]

I see there is a new driver for my Intel 4600 graphics adapter. I assume everything will go well, but I'm paranoid. How do I back out this maintenance (or do anything else, for that matter) if I no longer have a usable graphics adapter? I assume there must be some basic bios-based driver used during the boot process so I guess I could reinstall Windows at worst, but that seems like a bit of overkill.

What standard precautions are advised before updating a graphics driver?

Ok. I think I have the answer to my question, but I'd like it confirmed. I should be able to boot in safe mode and revert to the previous driver. It's unclear to me whether that works with a DVI-connected monitor, but I have an old VGA cable if I see nothing via DVI.
