direct rendering problem..

[brumal]

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: XF86DRIGetClientDriverName: 8.32.5 fglrx (screen 0)
libGL: OpenDriver: trying /usr/lib/xorg/modules/dri/fglrx_dri.so

ERROR: DDX driver fingerprint mismatch: got 0x3E32B6A8, but expected 0x32C4A39B
libGL error: InitDriver failed
X connection to :0.0 broken (explicit kill or server shutdown).

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