Thanks for your help!
I tried it with jackd -R -P70 -dalsa -dhw:0 -r44100 -p1024 -n2
but I still get ca 3-4 xruns per hour. But I can live with that.
I also just have a cheap Creative Labs Soundblaster PCI 128, maybe I
will by a better one. (maybe a m-audio Audiophile 2496 )
I also tried to change the IRQ for the soundcard, first by setting
IRQ 9 in the BIOS, end rhen also by setting the card into different PCI
slot, but with no succes. The /proc/interrupts is always showing
22: 16527 IO-APIC-fasteoi Ensoniq AudioPCI
but maybe this is the best solution

but for me it's not clear if "22: 16527 IO-APIC-fasteoi Ensoniq
AudioPCI" is a good interruppt assignemnet or not, and if it's possible to
IRQ 11 seems not to be used at all on my machine (btw a old and noisy one):

1: 1689 IO-APIC-edge i8042
