A (bit cleaned - drives, peripherals) dmesg is attached.

rmmod/modprobe does not show any errors - neither on STDERR, nor in syslog:

Only on rmmod the following line is added to dmesg:
# rmmod i915
[...] [drm] Module unloaded

# modprobe -v i915
insmod /lib/modules/2.6.32-5-686/kernel/drivers/gpu/drm/i915/i915.ko
modeset=1
