I've done some testing on an x201i and it seems the intel_powerclamp driver
("Package Level C-state Idle Injection for Intel CPUs") is responsible for
the difference in battery life. If that Linux driver is blacklisted battery
life drops to about the same levels as on OpenBSD.

If the processor throttles down it should also consume less energy, but it says 6W all the time though.
