At least two machines, the PPC mac99 and MIPS fulong2e, have an ATI gfx chip by default (Rage 128 Pro and M6/RV100 respectively) and guests running on these and the PMON2000 firmware of the fulong2e expect this to be available. Fortunately these are very similar chips so they can be mostly emulated in the same device model. This patch adds basic emulation of these ATI VGA chips. While this is incomplete and currently only enough to run the MIPS firmware and get framebuffer output with Linux, it allows the fulong2e board to work more like the real hardware and having it in QEMU in this state provides a way to experiment with it and allows others to contribute to improve it. It is compiled for all archs but only the fulong2e (which currently has no display output at all) is set to use it by default (in a separate patch).
