Wrapping up:
without any "tinkering", this is what I get:
root@kg-ibook# sysctl dev.cpu.0.freq_levels
dev.cpu.0.freq_levels: 1420/-1 710/-1
root@kg-ibook# sysctl dev.cpu.0.freq
dev.cpu.0.freq: 710

Simply adding
dev.cpu.0.freq=1420
to /etc/sysctl.conf, and the machine comes up with CPU at the full speed:
root@kg-ibook# sysctl dev.cpu.0.freq
dev.cpu.0.freq: 1420

So that's it.
