here is the anwer I received :-))
First of all: I was Terribly wrong
I did update my system and i915 Interrupts went down, but not due the
fact of the new kernel, but due the fact of having the NoDRI Option
still in my xorg.conf.
So the SuSE folks are right, i also didn't find any patch/fix/whatever
to make this go away!
Sorry for the wrong Information
sorry for the confusion.

I heard in the thinpad forum that this is actually a bug and that it is
fixed in 2.6.28.
However, it seems that in Ubuntu, the fix was propagated as a patch into
2.6.27 (intrepid-proposed, 2.6.27-11-generic x86_64?)
Is there any plan to propagate that change into the 2.6.27 suse kernel
Do you have a pointer to the fix in question? Without that it's hard
to tell. If the fix is simple enough then it should probably go in
2.6.27-stable and we get it from there.
