dmesg (rc8 with commit reverted)

Commit "populate master subdev pointer only when fully constructed" breaks
support for my 9600M GT (G96 on an Acer Aspire 6935G, bios 1.21), identified by
bisection and reverting it from the current git head (7d0d46da).

Instead of the framebuffer switching to the display's native resolution it just
stays at the one given by the bios and the boot comes to a halt after a few
seconds (with a few tasks, like wifi initialization, still being done
afterwards).

(I don't know the proper terminology; I hope that this description is clear
enough…)
