From what I have seen about the ATK0001 or the slightly newer version ATK0110, it is an Asus only driver mainly used for temp/system monitoring tools (don't remember which monitoring program it was I tried a long time ago, but it wouldn't read a M4A78 Pro properly until after installing the ATK0110). As for how it gets installed, it likely comes if/when you install any of the Asus software like Asus Probe, etc. You can also find it through Windows Update which as far as I know hasn't been one of the versions responsible for the BSOD's.
Not sure as it has been a while, but pretty sure that the version listed for download for the M4N78 PRO, ASUSTeK Computer Inc. - Motherboards- ASUS M4N78 PRO
is newer than the one through WU. As for installing, after unzipping you have to install it manually through Device Manager, Driver Install - Device Manager
P.S. No idea about any of the recent Asus Intel motherboards, but it looks like Asus has stopped using it with the latest AMD 9xx chipset based motherboards. Or at least I have no sign of it installed anywhere on my current M5A97 EVO (it also didn't show up the oen time I checked out the latest Asus suite).
