Well, I did:
1) deleted /Extra/nullcpupowermanagement.kext
2) added dsdt.aml to /Extra (from boot log I can see that it is loaded)
3) added to /Extra/org.chameleon.Boot.plist
GenerateCStates
Yes
GeneratePStates
Yes
The only one change is that now Intel HDA is detected in system information, but in Settings->Sound is still written no devices. Still wrong CPU (actually in boot log it is written correctly), no Ethernet, no Card reader, no actual sound.
I would appreciate any further help
