Well, we are using preempt because it's "the right way to go" and
worked reasonable well (well, we had some issues regarding the
speakup kernel modules but the problems seem to have been fixed in
recent versions of speakup). :)

As long as we don't experience any serious bugs or reasons to change
this behaviour preempt will stay the default in grml's kernel, yes.
