Probably, people capable of finding the way to patch by themselves, like donovan6000, will help me to find the way to patch this hard boiled pieces of binary.
1, by lunux, Phoenix SCT 2.1 from chinese OEM board.
No signs of normal locking code, appears to be a variation of old CpuPei patch in different module, but I don't know for sure.
2., by dajs, AMI UEFI from ECS P67H2-A3.
No sings of normal locking code at all. Can be CpuPei patch too.
3. X79/C062 BIOSes - no BIOS patch can provide native PM support, the kext itself needs to be patched. Nothing to do here now.
If anyone could help I'll be happy.

Phoenix SCT 2.1's MSR lock probably happens in either:
AMI UEFI ECS P67H2-A3's MSR lock probably happens in:
