3d acceleration don't work after upgrade. I changed platform(AMD Sempron -> Intel) and video card(radeon 9600 -> radeon x1600), after that i recompiled kernel, x, and fglrx driver.
When i trying to start any 3D application i'm getting message:
brumal@brumal $ LIBGL_DEBUG="verbose" glxgears

libGL error: InitDriver failed

also i'm getting similar error with glxinfo | grep direct, is says "DDX driver fingerprint mismatch blah-blah" and "direct rendering: No"
