ncpufreqd will not start but it doesn't print any errors either.

have you set the /etc/ncpufreqd.conf? also, have you started cpufrequtils as a daemon and loaded the various cpufreq modules?!

without them ncpufreqd won't work. to see if it starts try looking at the system log.

But
strange issue: I did a test: MAKEOPTS="-j" emerge amarok and guess
what the temp did not budge a degree over 50, but this morning as I'm
writing this my cpu is on 62% usage but the temp is 95 degrees.

it's impossible for the thermal to be at only 50 when compiling unlimited jobs. maybe the temp you're seeing is the core and not the thermal one. it makes sense that core is at 50° and thermal at 95°.

This
puzzles me. Stopping any emerge process did help, but last night it
went for hours with full 100% CPU load and now it overheats with
"-j1". It is clear, to me, that something somewhere is wicked.
LATER: I've just noticed that TZ01 in kima was 0 rebooting set it to
50 and now with emerge keeping the cpu at max speed and load gives me
only 55 degrees. So how I will do a kernel update maybe will fix my
problem, because it looks to me like it's comming from there. Isn't
it?

then the tz01 is the processor core thermal and not the thermal itself. then you should have another thermal zone other than TZ01. try looking in the /proc/acpi. or better do a ls -lR /proc/acpi > proc-contents.txt and append it here. it might be useful to see what your proc contains.
