Fallback to ODCM if neither acpicpu nor est are available, but don't
remove it. Why would you have to add things to cpu_info? If you think you
have to add extra things to cpuinfo you need to step back and rethink what
you're doing.
The user interfaces are not compatible.[1] ODCM is entirely different thing
compared to frequency scaling technologies. It saves no power whatsoever on
all three systems I have tested it on. (If I had a lab environment, a good
hypothesis to validate empirically would be that it actually might increase
the power consumption.) Consequently, in my opinion it should stay as a
logically distinctive feature (or preferably, removed).
