Breaking news. Late last night the Red Fire Chief, Jarred Land, has spoken. The Canon Birger mount, which lets you mount Canon still lenses,  gets the green light for NOT voiding the camera's global warranty.  Here is to hoping that the IMS and Visual Products BNCR adapter eventually get the "non voiding" warranty approval. 

 "At this point we are prepared to move forward with this.. I am pleased to announce that the Birger mount will not void the global camera warranty with the modifications Erik has done. Note though.. that any parts damaged from a potential electronic malfunction directly caused by the mount will not be covered.. and things like breaking the adjustable PL of the mount on removal/installation will not be covered ( since it never was designed to be removed). Because of the removal of the adjustable section is required, the Birger mount will not be RED Certified, but I think alot of you will be happy with the fact that it does not void your global camera warranty."
