But is it possible to track down the exact kernel version where those changes did happen? So we can find out at least what was changed (ioctl api for example). That's the information I'm trying to get here all the way, but nobody's willing to help. Maybe it's even possible to came up with some workaround on the kernelspace side but only if you know exactly what's wrong.
