Comment 36 for bug 391215

As described in my careless post to a duplicate bug report at

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/391705/comments/10

this happens to me as well. Acer SK20, Intel 845 graphics so I don't think it's just an nVidia issue.

The following lines from dmesg (attached) are interesting:

It looks like the option is not being ignored, but is failing to do what it should.
