原理：
dsdt让系统知道有这个显卡
FB告诉系统该显卡是如何处理信号的。
我是按这帖子做的：ATI 5系和6系显卡驱动&修改FB探讨
具体步骤：
1、查看显卡信息。
GPU-Z可以查看
2、将ID加入到ATI5000Controller.kext和AMDRadeonAccelerator.kext中
5470m的ID里面有，所以不需要添加
3、提取rom，修改你的接口信息
1、rom提取用aida64提取
2、用radeon_bios_decode和redsock_bios_decoder提取显卡信息
./radeon_bios_decode < 1002_68E0.rom
ATOM BIOS Rom:
SubsystemVendorID: 0x1462 SubsystemID: 0x1043
IOBaseAddress: 0xd800
Filename: BR35393.012

Subsystem Vendor ID: 1462
Subsystem ID: 1043
Object Header Structure Size: 140
Connector Object Table Offset: 2a
Router Object Table Offset: 0
Encoder Object Table Offset: 6c
Display Path Table Offset: 12
Connector Object Id [14] which is [LVDS]
encoder obj id [0x1e] which is [INTERNAL_UNIPHY (osx txmit 0x10 [duallink 0x0] enc 0x0)] linkb: false
Connector Object Id [5] which is [VGA]
encoder obj id [0x15] which is [INTERNAL_KLDSCP_DAC1 (osx txmit 0x00 enc 0x10?)] linkb: false
提取的信息如下：
txmit enc senseid
LVDS 10 00 01
VGA 00 10 08
LVDS前面部分
02 00 00 00 40 00 00 00 09 01 00 00
VGA前面部分
10 00 00 00 10 00 00 00 00 01 00 00
得到参数：
LVDS 02 00 00 00 40 00 00 00 09 01 00 00 10 00 00 01
VGA 10 00 00 00 10 00 00 00 00 01 00 00 00 10 01 08
#紫色表示显示输出顺序，00表示最优先输出
整理得到最终参数
0200000040000000090100001000000110000000100000000001000000100108
3、我们选用Zonalis参数
我把5系列的参数基本上都试了一遍，最后才试到这个6接口的参数，坑爹啊！
000400000406000000710000200106060004000004060000007100001000050500040000040600000071000021030204000400000406000000710000110201030004000004060000007100002205040200040000040600000071000012040301
我的只有2个接口，其他全部用0替代得到
020000004000000009010000100000011000000010000000000100000010010800000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
4、我们更改ATI5000Contrller.kext>Contents>MacOS> ATI5000Contrller
用0XED打开，选16进制，搜索Zonalis参数，替换为下面的参数，保存即可
4、笔记本A卡，且senseid为07
这一步就是改EDID，识别显示器用的，本LVDS接口是01，所以跳过
edid只是解决花屏或显示器识别问题，能正常进入桌面，说明edid暂时没什么问题。
5、加载你修改的FB
这一步就是改dsdt.aml。用DSDTSE修改
1、用IDSDT将dsdt和rom信息写在一起
2、更改相关参数
ATY后面原参数是Motmot。然后搜索Motmot，替换为Zonalis
再搜索ATY，往下拉，将@0,name，@1,name的ATY,Display-A、ATY,Display-B
之类的改为ATY,Zonalis。
将@0,name，@1,name，device_type 的 Buffer（xxx）里面的数字删掉
备注：我只有两个接口，所以只到@1,name
3、点编译，生成新dsdt.aml。放入/Extra下面即可
6、重启查看已QE
附：我改过的参数整理。
