ignore_nice_load is a feature of the ondemand governor.
The intel_pstate driver is seeing the load presented by the BOINC client
and is adjusting the pstate accordingly.

Is the intel_pstate driver a choice for a notebook and friends where a
grid software is running as a low-prio back ground job ?


Probably not.

Because the CPU will be running mostly at high(er) frequency - which
always results in a high temperature and short battery time.


It would be better IMHO if the client software limited the resources
it uses when the system is not on wall power but that is a seperate
discussion :-)
