[feature request] Reported CPU frequencies inaccurate for CPUs with different cores

[Markus Ueberall]

On an ODROID N2+ that is powered by an Amlogic S922X (Quad-core ARM Cortex-A73 and Dual-Core ARM Cortex-A53-based SoC), CPU cores 0+1 (slower) and 2-5 (faster) can have different speeds:

[2020-08-31T16:38:57+0200] root@odroid01:/tmp# cpufreq-info | grep -E "frequency is |The governor" | sort | uniq | sed -e 's|^ *||'
The governor "performance" may decide which speed to use
current CPU frequency is 2.02 GHz (asserted by call to hardware).
current CPU frequency is 2.40 GHz (asserted by call to hardware).

It looks like byobu either uses the CPU frequency of the first core or reports the slowest frequency. Is it possible to split the display for different *types* of cores? (Something along the lines of "2x2.0GHz/4x2.4GHz"?)
