a did put some printks here and there and psb_driver_init seems to never return from gma_backlight_init.
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.
and back to the original issue, with 3.5 the laptop suspends to ram just fine! finally this vaio X may be of some use!!
I can test patches for the errata call issue if you need any confirmation.
