It appears as if Mutter doesn't allow for custom modelines and passes the
kernel's modelines through. I've tried the following kernel command line
parameters:

  video=2560x1440MR at 59
  video=HDMI-A-2:2560x1440R

Unfortunately the pixel clock is still limited to 165 MHz.

Ville, is there a way I can force a mode via parameters?
