I compiled agpgart and intel-agp as modules. Works better, since the kernel    
doesn't oops again. It just gives an     
    
Jul 29 22:08:54 thinkpad kernel: [drm:savage_bci_wait_event_shadow] *ERROR*    
failed!    
Jul 29 22:08:54 thinkpad kernel: [drm]    status=0x000100a8, e=0x00aa    
    
Then the savage-driver resets.    
    
If I set Option "DmaType" "PCI" in xorg.conf, glxgears works with 330    
fps. glxinfo shows  direct rendering enabled  
 
I can provide with several logs, if needed.

there seems to be a problem with savage and agp on IBM laptops.  several others
have reported the same problem.  I've noticed similar problems on my T20.  I
looked into it, but didn't notice anything apparent.  you might try forcing
shadowstatus off in your config (you may have to edit the code, savage_driver.c
in the DDX, I don't know if it'll let you turn shadowstatus off and still enable
the DRI anymore), I seem to recall hearing the shadowstatus was problematic on
ibm laptops.

Disabling shadow status in the config file should work. DRI vs. no DRI is only
supposed to change the default setting. See also the manual page.

I had posted a similar observation, see:

   http://www.mail-archive.com/dri-devel%40lists.sourceforge.net/msg24425=
.html.
Interestingly, disabling "SELinux" allowed me to achieve normal operation=
.

Direct rendering on my "IBM ThinkPad T23" is up and running
after booting the machine. The video chip is an "S3 Inc.
SuperSavage IX/C SDR rev 5". "glxinfo" reports that direct
rendering is enabled and 3D hardware acceleration is ok.
However, after logging out and in again, execution of
"glxinfo" triggers a segmentation fault. "DRI" enabled
applications make the "X" session abort instantaneously.
After rebuilding the "DRM" kernel modules for current
version 1.0.1, the problem goes away. Seems to be identical
to this bug. Can you try with current "DRM"? I am using
modular "X" 6.99.99.902 (7.0.0 RC2) on FC5 test1.

The strange thing here is that even without updating the kernel "DRM"
the problem goes away by merely manually loading the already present
system kernel module "savage.ko" corresponding to "DRM" version 1.0.0.
I have noticed that appending "/sbin/modprobe savage" to "rc.sysinit"
on my FC4 system (2.6.14-1.1653_FC4) makes it impossible to me to
trigger any kernel oops or segmentation fault by launching "OpenGL"
applications such as "glxinfo" or "glxgears" after successive "X"
sessions or even after restarting the "X" server.

Seems to be fixed in kernel 2.6.15-git9 through DRM upstream
update to version 1.0.1 committed by D. Airlie. Please check!
