Hello there again
I've just added the tacho display for CPUfreq gadget. It looks better but it is no the main reason I am writing here. Since BL 4 the tacho hand was blocked with powersave governour driver added in Ubuntu version the Bodhi is based on. It is called intel_pstate and the old cpufreq module did not respect it. It is possible to disable it in grub setup but I wanted to have an universal solution. I made some code changes in source after some studying but then I found the better solution in E22 thus I ported it to Moksha. Now it works as you got used to in BL 3x.

Enjoy
PS: of course the solution is working for all themes we maintain. The moksha code is under heavy development these days mainly by Ylee and partly by me so take it as a teaser for BL 5.1 release
