I was forced to, because I ran out of PCI-Slots, so an aditional SCSI 
card would be very complicated to plug in. 

USB is quit fine here. I think there must be a possible solution,
if I disconnect my USB bus and connect it onto my Notebook (which came 
delivered with Wintrash 98, because HP is to silly to sell 
Linux-Preinstalled Notebooks, they are abusing the customer rights and 
force to buy M$), the scanner does work like a charm in USB.

I'll use a stopwatch on the Scanner speed, perhaps ther is a way to 
reduce the scan speed and HP does not document it. Would not be the first 
time of the HP compyn to kick the ass of Linux, to push illegally M$.

That's really not an option. Would you cut off a leg or the half of the 
brain ?
I tried it with a NON-SPM Kernel, but it happens also.
