According to the debugfs, your defaults should be effective:
sandybridge:~$ cat /sys/kernel/debug/dri/1/i915_ring_freq_table
GPU freq Effective CPU freq
850 0 -> 1600
900 0 -> 1700
950 0 -> 1800
1000 0 -> 1800
1050 0 -> 1900
1100 0 -> 2000
I'll give the tyres another kick and see if I can spot any differences.
