QEMU patches for Raspberry Pi emulation

About
================================================================================
This project aims at providing a basic chipset emulation of the Raspberry Pi,
to help low-level programmers or operating system developers in their tasks.
[..]
Emulated chipset parts are at the time of this writing: - System Timer. - UART. - Mailbox system. - Framebuffer interface. - DMA. - eMMC SD host controller.
The emulation is quite incomplete for many parts, however it is advanced enough to boot a Pi-targetted Linux kernel, along with a SD image of a compatible Linux distribution.
Here is the new command line:
/path/to/qemu-system-arm -kernel kernel.img -cpu arm1176 -m 512
-M raspi -no-reboot -serial stdio -sd 2012-12-16-wheezy-raspbian.img
-device usb-kbd -device usb-mouse
