[PATCH] crash in aty128_set_lcd_enable() on PowerBook

Current Linus tree crashes in aty128_set_lcd_enable() because par->pdev
is NULL. This happens since at least a week. Call trace is:

aty128_set_lcd_enable
aty128fb_set_par
fbcon_init
visual_init
take_over_console
fbcon_takeover
notifier_call_chain
blocking_notifier_call_chain
register_framebuffer
aty128fb_probe
pci_device_probe
bus_for_each_dev
driver_attach
bus_add_driver
driver_register
__pci_register_driver
aty128fb_init
init
kernel_thread

- info->fix was assigned twice.

- par->vram_size is assigned in aty128_probe(), no need to redo it again
  in aty128_init()

- register_framebuffer() uses uninitialized struct members, move it past
  par->pdev assignment and past aty128_bl_init().
