Hmm... ksoftirqd/0 (or also ksoftirqd/1 on 2cpu SMP) are already SCHED_OTHER by default, at least on both of my boxes that are running RT-V0.4.1 now.
Should I try the other way around? Lets see... 'chrt -p -f 90 `pidof ksoftirwd/0`',... yes, apparentely the xrun rate seems to decrease into half, but IMHO not conclusive enough, thought.
