Gerd Hoffmann 136e2612bd ati-vga: fix ati_read() 
Cut & paste bug probably.  Had no bad effect so far because the code
doesn't read registers larger than 0x100.

Gerd Hoffmann 34b6ecc160 vga: add atiext driver 
Supports qemu emulated ati cards.  They have been added in qemu 4.0.
Acceleration support (in qemu) is pretty rough still.  A simple
framebuffer works fine though.

Available models:
 * ati rage 128 pro
 * ati rv100
