Thanks a lot for answering.

Oh, I already filed a bug report some hours ago against 
libgl1-mesa-dri :

I'm not sure what you mean by DRM 1.23: But a just a few days old
relatively fresh git kernel here says this in kern.log (when
rebooting after the mentioned crash probably --> the wrong 'Jan 1' date):

Jan  1 01:00:53 debby1-6 kernel: Inspecting /boot/System.map-2.6.17-rc3-gf358166a-dirty
Jan  1 01:00:53 debby1-6 kernel: Loaded 19106 symbols from
/boot/System.map-2.6.17-rc3-gf358166a-dirty.
  
                 [ ... ]

Jan  1 01:12:08 debby1-6 kernel: [  715.607451] [drm] Initialized drm 1.0.1 20051102
Jan  1 01:12:08 debby1-6 kernel: [  715.640230] [drm] Initialized radeon 1.24.0 20060225 on minor 0

Does the above mean that this kernel still has drm 1.0.1 ?

Or is it old xorg stuff that is being loaded at the time of the
kern.log above? 

$ zgrep DRM /proc/config.gz 
CONFIG_DRM=m
# CONFIG_DRM_TDFX is not set
# CONFIG_DRM_R128 is not set
CONFIG_DRM_RADEON=m
# CONFIG_DRM_MGA is not set
# CONFIG_DRM_SIS is not set
# CONFIG_DRM_VIA is not set
# CONFIG_DRM_SAVAGE is not set

So I'm not even sure what was going on when the system crashed: Were
the kernel DRM modules from above loaded, or some DRM from xorg?

Actually I'd bet now they were part of an xorg package ... :) Because the
sources for the running kernel, in drivers/char/drm/radeon_drv.h, say

 * 1.24- Add general-purpose packet for manipulating scratch registers (r300)

But I can only guess ... :)

Yes and No :)

No: I really thought I saw some date of 2004 when rebooting. I was
wondering about that as I was used to see something like 1904 in
situations like that.

Yes: After having a look to my log files I'm
not sure of that anymore, as one kdm.log clearly has one line with that:

(==) Log file: "/var/log/Xorg.0.log", Time: Fri Jan  1 01:12:07 1904


Thanks in anticipation
Wolfgang
