I can't get another kernel than 2.6.16, because all the xen patches rely on this version and I need xen. I will try the newest from the 2.6.16.y series, give me another day to try it, I think xen provided the oldest 2.6.16 one it could find. I'll tell you if I got further with that. Maybe it's also related with the "nobody cared" phenomena from http://www.ussg.iu.edu/hypermail/linux/kernel/0610.1/0101.html - I suspect the irq issue to be Supermicro related.
