Comment 5 for bug 585258

I ended up using a precompiled 2.6.34 mainline kernel instead of compiling myself upstream sources (they told me it's basically the same thing).

Test results: the same as 2.6.32, Fn+F8 does nothing in X and outputs a "p" in gnome-terminal. Following suggestions on the gmane linux.ubuntu.kernel.devel.general group, I've already tried to add acpi_osi="!Windows 2009" boot argument but it does not solve the problem in 2.6.32 nor 2.6.34. either.
