9 * This driver supports the following ATI graphics chips:
12 * To do: add support for
13 * - ATI Rage128 (from aty128fb.c)
14 * - ATI Radeon (from radeonfb.c)
16 * This driver is partly based on the PowerMac console driver:

42 - cursor support on all cards and all ramdacs.
43 - cursor parameters controlable via ioctl()s.
44 - guess PLL and MCLK based on the original PLL register values initialized
45 by Open Firmware (if they are initialized). BIOS is done
47 (Anyone with Mac to help with this?)
