Hi,
This list is the wrong one, you want either the xorg list or lkml.
Having said that, I think the problem with vertical retrace is that the
information isn't available to the X server either: the kernel needs to
expose the event, perhaps by letting apps block on a file descriptor
until the vertical retrace interval begins. So maybe you should talk to
the kernel people?
