Thank you, thank you, thank you! Same Hardware, same problem, fixed by installing your DSDT over EDP 1.9 (Not the preboot image, just the dsdt.aml - installed via -x in 1024x768, ran EDP, ran Lizard, pointed to DSDT, works like a charme)
BTW: A07 BIOS here, I was just lazy and tried before flashing, works flawlessly.
Best regards, Leo
