no luck. i've let myself to change subsystem device condition to match data shown in log (RS400 0x1002:0x5A41 0x1043:0x81C8 ). then - first if is taken twice, but ddc_i2c->valid is true in both cases. after planting DRM_ERROR call on top of combios_setup_i2c_bus(), like this: DRM_ERROR("setup bus: %d %d %d \n", (int)ddc, clk_mask, data_mask);

, i got whats in attachment.

Try this patch instead. I misread the bios tables.

--- Comment #9 from Przemek Tomczyk tomczyk.przemek@gmail.com 2012-07-20 17:14:13 UTC --- neither of those worked. kern.log output is now the same as in first attachement: [drm:radeon_add_legacy_connector] *ERROR* DVI: Failed to assign ddc bus! Check dmesg for i2c errors.

and then

[drm] Connector 1: [drm] DVI-D [drm] HPD2 [drm] DDC: no ddc bus - possible BIOS bug - please report to xorg-driver-ati@lists.x.org [drm] Encoders: [drm] DFP2: INTERNAL_DVO1

How about this one? If it doesn't work, try commenting out the first *ddc_i2c line and uncommenting the second:

+ *ddc_i2c = combios_setup_i2c_bus(rdev, DDC_DVI, 0, 0); + //*ddc_i2c = combios_setup_i2c_bus(rdev, DDC_VGA, 0, 0);

Let me know if either of those work.
