When i say your mail i vaguely remembered something, and it seems that
i wrote this support
(http://cgit.freedesktop.org/xorg/xserver/commit/?id=974db58f5b730c3770ee461665a02dd4334d1dea)
based on an idea that i had back then. But it you need a video driver
to actually activate this functionality. So you should check the
sourcecode of the driver that you are using if you can. To be honest i
don't know if anyone actually used this.
