Sorry for the delay, but I'm not in charge of that machine and
therefore I can't spend much time on it.
The problem were ridicuously many zs interrupts, as vmstat (-i) showed :

23 of you had an advice for me, I thank them all. The advices were :
- change keyboard and mouse (which we did with some success)
- install patch 100259-03, which corrects an NFS problem with extremely
large files
- upgrade to 4.1.2
- boot without keyboard
- getty processes for serial devices not connected
- check for noise on tty cables (we have none attached)
- check for noise on ethernet
- swap CPU board (no warranty on it)
- check external SCSI devices for incorrect 12 volt power (none attached)
- check ROM revision, which has to ge greater than 1.0 to connect serial devices
The machine was powercycled several times with and without keyboard, half of the
time not coming up at all, so we probablely have a CPU problem. At the moment it
is running with a swapped keyboard and a lot better, but not completely normal :
interrupt total rate

As they can't afford a CPU at the moment, they'll leave the machine as it is now.
