It's gone from 2.6.31-rc2, but even the in-tree drivers break, so I
think we have to put it back for 2.6.31 (I've sent Linus the pull
request already).
I do intend to remove it again for 2.6.32 though, and I filed
http://bugzilla.kernel.org/show_bug.cgi?id=13721
For now it's got a clearer description ("Workaround broken graphics
drivers") and defaults to 'n'.
