+ * This is the power management code for ATI radeon chipsets. It contains
+ * some dynamic clock PM enable/disable code similar to what X.org does,
+ * some D2-state (APM-style) sleep/wakeup code for use on some PowerMacs,
+ * and the necessary bits to re-initialize from scratch a few chips found
+ * on PowerMacs as well. The later could be extended to more platforms
+ * provided the memory controller configuration code be made more generic,
+ * and you can get the proper mode register commands for your RAMs.
+ * Those things may be found in the BIOS image...
