Chris I can confirm that the bug exists after having updated my bios (2.08 -> 2.10). I have also checked the new bios with the upstream kernel for completeness.
The problem remains identical to the description given in my initial report. I have removed the outdated bios tag and set this back to confirmed (which I hope is the correct procedure).
