Does this mean it works for you? Or do you have
BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_KMSRO=y integrated
and it does not work for you (take care to not mix it with
BR2_PACKAGE_MESA3D_GALLIUM_KMSRO)?
I have a hifiberry-os running with the local gui on hdmi:
$ ps aux

The only thing I have to hack was the resize-partitions for the extra large image ;-)
