When trying to run 2.5.99.1 with todays libdrm on xserver 1.5.3 with kernel 2.6.27.10 I can only get a working KDE 4.2 beta environment with XAA or EXA (hmm, the latter seems to work while I write this, weird) enabled. Chipset is Intel 852/855GM. With UXA I can get a plain xsession, run x11perf -aa10text or glxgears but kdm reboots the server constantly ending with a permanent system unavailability. Logs attached

UXA needs GEM kernel, i.e. 2.6.28 (or current -rc).
