cool, I didn't know anything about this and after receiving your mail I
searched by using Google, so I think Mitsch should take care, if the
interrupts at all are delivered.
I've taken a look at my /proc/interupts
0: 212 0 IO-APIC-edge timer
1: 10 17584 IO-APIC-edge i8042

I don't use the parallel port and I think "parport0" means the parallel
port. The 0 for each core of my CPU means, that no core has taken care
of it, as far as I understand this. So there might be no need to change
anything, because it seems to be possible, that Mitsch's CPU isn't on
load by the unused devices.
I wouldn't change any scripts, resp. add anything to the blacklist, if
there isn't the need to do this and I wouldn't know what is what, e.g.
it wouldn't be enjoyable if there will be no IRQ for the keyboard.
