So what to do here now? Matthew had some concerns that this one might break other machines, but it definitely fixes the Lenovo ThinkPads. Shall it be put into -mm until we find offending machines we can debug and provide a better solution? I try to find a Dell or Toshiba with video extensions (this could get difficult) and try a bit there... If time is running out for 2.6.24, maybe we can add this check with a Lenovo dmi check added, so that at least those work as expected and remove it if we find a safer way of detecting fake devices? > This will fix the issue with multiple VID devices in /proc but the rest > will still occur, of course this is no fault of ACPI video.

Don't know whether it helps for your X problem you should probably ask on a X-server related list for that..., updating the BIOS first is probably a good idea and Lenovo fortunately provides BIOS iso's.
