5830 The Real Question: BIOS Update

Reading though the article at It was said that the 5830 and the 5870 have the same GPU core except the core was "crippled to the new specification and dubbed Cypress LE. In fact, AMD's power usage specifications suggest that the Radeon HD 5830 will be based on the high-end Radeon HD 5870 card instead of the smaller 5850." So theoretically it is a 5870 with GPU parts disabled to make it a 5830. My question is we have seen some success with the 5850 BIOS updates to a 5870 however it doesn't affect the number of shaders. Has anyone gotten a hold of one of these cards and tried a 5870 BIOS update on it to see if it could reactivate these parts of the GPU? We know it is possible to unlock parts of the AMD processors, for instance the Phenom II x2 550 can be unlocked into a Phenom II x4 B50 however the reasons these parts are locked are totally unrelated to my understanding. Considering originally the processor cores were locked due to quality control. However these GPU chips seem to have locked parts on purpose seeming just shutting down parts of perfectly good GPU's.

This was just something I have been thinking about rather hard and without the extra money to just try it I just figured I would ask and see if anyone else has had this idea and was actually able to try it, or to get the idea out there to see if anyone was willing to try it.
