I have two Radeon chips here, an M6 in my old laptop and a 9200 in my desktop system. On the M6 there is nothing on the monid bus. On the 9200, the monid bus doesn't even work, every access results in timeout. The radeonfb driver doesn't even look for EDID EEPROMs on that bus (except in debug code.) So I'm curious why you create this i2c bus if you don't need it. Have you ever seen a Radeon adapter where there is something on that bus?
