ha! that gave me a good lead.
The problem is not gma_backlight_init but rather psb_modeset_init that
calls the errata for the chip that in turn sets the brightness before
any initialization is done.
Commenting out the call to dev_priv->ops->errata in framebuffer.c makes
boot get to the end like it used to on 3.4. It seems to be just an
ordering problem in the end.
