The driver will already refuse to load with nomodeset for GEN6+ for
quite some time now. On old platforms UMS would still work before this
patch, but afaik there was a decision to stop supporting UMS. Note that
this doesn't mean "recovery mode" or equivalently nomodeset will break
booting, it just means user space will fall back to vesa/vga or text
mode.
