Adding this line to OS definition fixes the initial issue.

However, you still need to manually add the kernel module and start the corefreqd daemon as a root.

```
$ corefreq-cli
Daemon connection error code 2
corefreq-ro-shm: 'No such file or directory' @ line 19075
$ corefreqd
corefreqd execution error code 13
Permission denied @ line 8002
$ sudo -E corefreqd
Password:
Driver connection error code 2
/dev/corefreqk: 'No such file or directory' @ line 7998
$ sudo -E modprobe corefreqk
$ sudo -E corefreqd &
CoreFreq Daemon 1.90.1  Copyright (C) 2015-2022 CYRIL INGENIERIE
$ corefreq-cli
# Now it launches :-)
```
So maybe a service would be handy, what do you think?
