Issue #327 has been updated by Joel Linn.
I can also confirm this, I get *ACPI_BIOS_ERROR 0x1000 0x0 0x0 0x2000* and applying the mentioned change does the trick for me. Sandy Bridge H61 Express i3-3220, no secondary GPU, libgfxinit

this line .. OperationRegion (OPRG, SystemMemory, ASLS, 0x2000) the 0x2000 will cause BSOD ACPI_BIOS_ERROR when booting installer, os, etc
