I had this problem after I updated first kernel after 2.6.38. So I always kept a copy of 2.6.38. All the 3.0 and even 3.0.1(custom compiled) had this problem. 2.6.38 has graphics glitches, but xorg- edgers has made it usable enough. The 3.0 kernels are good for graphics performance but drains away the power. Since, I have dual graphics card(ATI and one that of sandy bridge), I though problem was because of me having two cards, but it seems all sandy bridge users are having the power regression problem. I had written this post http://ubuntuforums.org/showthread.php?t=1817374. I tried i915.i915_enable_rc6=1 option, it had no effect at all.
