The value of VCO_MIN comes from the Intel PRM for similar GPUs.

Instead of changing VCO_MIN, could you try setting N_MIN=1, N_MAX=6 and M1_MAX=22? I'll test it on my own hardware tomorrow.

Thanks for your suggestion.

With "N_MIN=1, N_MAX=6 and M1_MAX=22", i get a refresh rate of 59.9Hz.

Those values come from the i915 driver and should work fine for us as well. I had no problems at my end so I'll submit a patch for this.
