Looking around, I can see, this problem ist reported elsewhere as well.
Just found it for debian and archlinux.

When trying to cure it by explicitely loading module i915 or the previous
versions of intel driver from extra deposit, I encountered compatibility
problems, which looks like a different problem.

We think we've got this one figured out too, but time will tell.
Patience, grasshopper :)

Cannot offer a cure the correct (analytical) way, but for me it works now,
after I recurred to a previous .config for fresh compilation of kernel
2.6.33, via 'make oldconfig' (plus 'make menuconfig'). When compiling from
distribution .config, somehow I fell into the trap of losing new way of
access to ATA harddrive as /dev/sdax, so I did not look around for much
configuration inside this version, after I had a fall-back version
available.

For kernel configuration of module i915, the extra tick has to be applied
(in .config: 'CONFIG_DRM_I915_KMS=y'). Now module i915 could be loaded and
in consequence I could configure 'intel' in xorg.conf, this looks good now.

Re-arranged the items in xorg.conf a bit, as well, after reading in manpage,
so to have two screens (laptop interal plus external) configured in
two different blocks now.
