The Rominator just finished experiments with flashing pc gtx285 with mac’s rom.

good news - it works, link speed is 5 GT/s (pcie 2.0), unlike 2.5 GT/s on flashed 4870

bad news - you need some soldering, because size of mac rom is 156kb, but size of typical pc gtx285 rom chip -128kb, so need to replace it with 256k rom chip before flashing.
