Just for the record, I am successfully using a 20 July DRMKMS kernel on a
desktop amd64 box with a 
    Device Name: Ivy Bridge Integrated Graphics Device (0x0162)

The Sandy bridge laptop is fine with an external monitor but doesn't
detect its built-in screen. Neither panic, and glxgears is very happy.
