and when forced custom combios_setup_i2c_bus call by commenting out
"ddc_i2c->valid == false" (was it wise?) got this connectors info, but still
DVI output is dead.

kern.log after patch applied

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.

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]   HPD2
[drm]   DDC: no ddc bus - possible BIOS bug - please report to

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.
