Linux:: Xorg and Ati

I am using debian, the sid version and I have just upgrade... But it seems that there is a big issue with the new version of Xorg. When I try to launch the X server, it complains that the module ABI (0) doesn't match the server's version (1) . and after that it explained that it is unable to load the module ati. So now, I have no more Xserver: I have to do everything with the command line... Enjoy Linux Power
