We have done some tests on three of Intel + nVidia configuration systems with OEM _OSI strings removed - while some bugs are still observed, ex. one out of three has suspend/resume issues, no system crashes were observed - the biggest issue that worries us. The positive results give us confident to ack the removal of the OEM _OSI strings. While our tests were not able to cover all possible I+N systems, we are sure we can fix issues along the way. If there aren't systems that cannot be fixed without these OEM _OSI strings, these strings should probably enable with DMI quirks (possible future patches) so they won't affect others.
