Ok, so the problem is definitely not the mainline kernel, but could still be our patches.
The laptop has been tested with a live DVD of Sabayon linux with kernel 2.6.31-sabayon #1 on i686 arch, it is based on gentoo 2.0.1, and uses GNOME 2.28.0.
Will try to test other distros to narrow down the issue.
