Patch kexts and optimizing

[Bob_]

Hi everyone. I managed to install Yosemite with Clover bootloader and the main things work fine. However, there are a few things to fix...
First of all i wanted to patch my AMD5000Controller and AMDRadeonX3000 kexts on-the-fly; i just need to add my vga to the info.plist inside those kexts. so i put this inside config.plist:

 

<dict>
	<key>Name</key>
	<string>AMD5000Controller</string>
	<key>InfoPlistPatch</key>
    	<true/>
	<key>Find</key>
    	<string>68A11002</string>                       
    	<key>Replace</key>
    	<string>68BE1002</string>
</dict>
<dict>
    	<key>Name</key>
    	<string>AMDRadeonX3000</string>
	<key>InfoPlistPatch</key>
    	<true/>
    	<key>Find</key>
    	<string>68A11002</string>                       
    	<key>Replace</key>
    	<string>68BE1002</string>
</dict>

buuuuut, it does not work. i tried both with <data> and <string>, nothing. Also it does not even work if i just put the modified kexts inside 10.10 kexts clover's folder. I need to keep the modded kexts in s/l/e... why?

Second, wake doesn't work. Sleep works but when i wake up i only get a black screen.

Third, i read that since mavericks the kext AppleIntelCPUPowerManagement (and others) is not needed and loaded anymore, cause is all managed by Xnu CPU Power Management. In my case however the kext is loaded, and sysctl machdep.xcpm.mode gives me 0. This seems not causing any problem, but... I don't know. Maybe something's wrong?


To solve these i tried to generate and use dsdt and ssdt but didn't make any difference at all, so i erased them. CPU is working perfectly, i think... I have all the p-states.
I also tried patching aicpupm kext to solve the sleep problem but it messed me some things so i put back the original one.

Could anyone help me in any way?
Thanks
