Although Intel's current spec[1] shows the OpRegion structure version as being the top 16 bits of the field, Intel's Windows drivers require the OpRegion structure version to be in the top 8 bits of the field when not using a VGA BIOS (eg, NGI or GOP driver). As the Linux i915 driver only checks that the version is >= 2, there is no change in functionality there. This change effectively matches Intel's implementation in TianoCore, where the version is set to 0x0200 << 16.
