ACPI regression: New Acer workarounds break Samsung NP900X

[Ortwin GlÃck]

Lv,

These two patches introduce a regression for Samsung notebooks and they no 
longer get ACPI interrupts for plugging the power adapter or LID switches.

Multiple people have verified that reverting these patches makes the regression 
go away.
