apparently, it does:
@@ -150,6 +150,8 @@ static u32 asle_set_backlight(struct drm_device *dev, u32 bclp)
struct opregion_asle *asle = dev_priv->opregion.asle;
+return ASLE_BACKLIGHT_FAILED; // rday
if (!(bclp & ASLE_BCLP_VALID))
gives me a good boot. this is the diff with relation to the recently
tagged 2.6.38-rc3. anything else you want me to test?
