У меня тоже грелся) Сделал: sudo cpufreq-set -g ondemand, потом перезагрузился и по cpufreq-info имею:
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 800 MHz - 1.60 GHz
available frequency steps: 1.60 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 800 MHz and 1.60 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
cpufreq stats: 1.60 GHz:0,00%, 1.33 GHz:0,00%, 1.07 GHz:0,00%, 800 MHz:0,00% (2027)

Почти все время 800 МГц, вполне хватает. Атом 1.6. У жены на НР550 тоже корка какая-то, сделал то же самое - не греется)
