* This driver supports the following ATI graphics chips:
|
|
* - ATI Mach64
|
|
*
|
|
* To do: add support for

|
|

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