On the Acer P450-G2-M, after the user opens the laptop lid and the device
resumes from S3 deep sleep, the screen remains dark for a few seconds.
If the user presses a keyboard key while the screen is still dark, the
mouse and keyboard stop functioning.

To fix this bug, enable the noloop quirk.

Are you sure that you want to disable loop and not mux mode? The only
time we issue the "AUX LOOP" command on resume is when we try to restore
MUX configuration...
