That is 'cupspeed' - i.e /etc/init.d/cpuspeed [as in the subject of this thread]

Check /usr/sbin/cpuspeed --help
[and modify the defult behavior by editing /etc/cpuspeed.conf]
I've used '-i 1' - and I would need [RFE] an option to eliminate the
intermediate stages [like cpudyn]

Don't know how to specify 'stay in max performance mode - when
connected to battery'. It can be done manually with 'killall -SIGUSR1
cpuspeed'
