Ok, I've downloaded the latest CVS and done some testing. It seems that 
ibwait is now working, for one card anyway :) ... I can read from and write 
to the GPIB-devices on the bus. 
   The test with the ISA card worked as I wanted, the performance was not the 
same as for the NI PCI-GPIB with their own driver and library, but I'll blame 
that on the hardware.
   I could not get it to work with the PCI card. ibwait returned when the 
timeout expired. There could probably be an confiuration error from my side. 

I experienced a hard-lock of my computer when I removed the tnt4882 module 
from the kernel.

I've in the middle of another project at this time so I don't have that much 
time to test this but it seems that ibwait is working, atleast for the PCIIA 
ISA card.

Great work!
