Yes, this is for the older version of DV6/DV7, without Sandy Bridge.
Just replace that part with your own DSDT fix for ATI (or whatever else). Make sure to add new line endings (\n) at the end of every line. There might be some other changes required, but I don't have the platform to test.

gsly, what about that beer? You said you don't turn down beer, so is there any way I can buy you one or two?
The parser does fail on the decompiled DV6 DSL, that's why that nasty hack is needed.
