%%%--- Operating System, Graphics card ---
Arch Linux 64-bit
Nvidia GTX 295

- Blender version with error, and version that worked ---

Error: Blender 2.66.0 r54697
Working: Blender 2.65 r53177

- Short description of error ---

Normals can't be set using foreach_set in Blender 2.66. For example, something like this doesn't work anymore:
verts.foreach_set("normal", normal_list)

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Open Blender and make sure default "Cube" is available.
Copy this code into the Text Editor (or open the attached Blend file):

import bpy
import random

verts = bpy.data.meshes["Cube"].vertices
for v in verts:

  print(v.normal)

print('----------')
random_normals = [random.uniform(-1.0, 1.0) for i in range(0, 24)]
verts.foreach_set("normal", random_normals)
for v in verts:

  print(v.normal)

Hit the "Run Script" button.
Verify that normals weren't updated in the console.%%%
