Two more comments on this patch, sorry for the noise...

1) With this patch, running "reboot" or "shutdown -r now" no longer
works; the system hangs. Reboot works fine without this patch, in
next-20120708.

2) U-Boot initializes the LCD, and prints to it. This is left running
when the kernel is booted, and the kernel doesn't reprogram the HW, so
the LCD continues to scan out some "random" area of memory. Typically,
this then gets used and so the LCD shows random patterns. In today's
linux-next it seems to be turned black though; not sure why that's
happening. Either way, this patch turns the whole LCD completely white.
Is that an expected change?
