There is a patch for this problem proposed for upstream kernel.
See https://lkml.org/lkml/2011/7/20/38
I've backported the patch to Ubuntu Natty and it has been successfully tested by Stephen_m64 (see http://ubuntuforums.org/showthread.php?t=1607778).
You will find the test kernel in https://launchpad.net/~rdratlos/+archive/ppa-asus-m2a-fix.
