Is it ok if you just comment out gma_backlight_init (at which point it should just skip backlight handling and leave the firmware configured one)
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.
