Is there a bug report tracking the power regression in the 2.6.38 kernel?

Question

I'm looking for an official bugtracker entry (either ubuntu, or kernel) which tracks the story of power usage regression described in:

• http://www.phoronix.com/scan.php?page=article&item=linux_mobile_uffda
• http://www.phoronix.com/scan.php?page=article&item=ubuntu_natty_power

I couldn't find any actual links or articles about resolution of the problem. Any pointers to official sources would be appreciated.
