Right, if your system bluescreens with the disk controller in AHCI mode, all you have to do is change it back. The most that will happen is your system won't boot. Data loss shouldn't happen.
It's still a good idea to back up important data first, just in case.
But you shouldn't get a bluescreen. Windows 7 includes a generic AHCI driver, so it should start right up, whether your disk controller is in AHCI mode or IDE mode.
