If I switch to to 'turbomode' using the cpufreq-indicator, turbostat
shows the cpus still stuck at 800MHz:
cor CPU%c0 GHz TSC SMI%c1%c3%c6%c7 CTMP PTMP %pc2

11.67 0.80 2.00 0 13.31 0.21 0.00 74.82 53 53 2.75
Rebooting with intel_pstate=enable has fixed the issue and vastly
improved the responsiveness of this laptop.
** Summary changed:
- CPUs stuck at minimum frequency with ondemand cpufreq governor, even after
reboot
+ ondemand cpufreq governor does not scale CPU freq on Sandybridge
