Working from the all three applied state of your last dump, the diff against
no-randr12 shows a few things still, so (on top of the previous changes):
0) do the PLL_SELECT change (unlikely to do anything, but still)
1) nv_crtc.c:1454 regp->fp_vert_regs[REG_DISP_CRTC] = 0x41a;
2) nv_bios.c:2808 
if (pNv->dcb_table.entry[dcb_entry].type == OUTPUT_LVDS)
        (i.e. remove dual_link test)
 & nv_crtc.c:1533 remove "if" test so 
regp->fp_control[nv_crtc->head] |= (8 << 28) is always set
3) nv_bios.c:3152 lvdsmanufacturerindex = 1;
