/*
* This driver handles dedicated ATI GPU, which can be found in:
* - Nintendo GameCube (ATI LSI Flipper @ 162 MHz)
* - Nintendo Wii (ATI Hollywood @ 243 MHz)
*
* Flipper and Hollywood chipsets are pretty similar, except from clock speed:
* - Embedded framebuffer is 2MB.
* - Texture cache is 1MB.
* - Vertex cache is 0.1 MB.
* - Framebuffer is YUY2, not RGB.
* - Best resolution is 480p (854x480)
