acpica and the Intel display driver tries to use the Intel Opregion simultaneously on Genode, which is not supported nor wanted for IO_MEM region as which it is handled. Attempts to remove the access to the region was not successful, since some SSDT table contains ACPI AML code which is executed regularly and read/write the Opregion. The patch adds support to make a copy of the Intel Opregion and report it as is. The copy was sufficient to make the Intel display driver working to find and lookup the Intel VBT (video bios table) information to setup all connectors on a Fujitsu U7411 docking station. Issue #4531
