Thanks - I forgot about lszorro :-)

Slot address is just the top two bytes of the base address - the d1 and 
c1 part of the proc output is meaningless?

So we have cyberstorm, cyberstormII and blz2060 drivers to port? What is 
the difference between the cyberstorm ones?
DMA setup looks fairly similar to me (blz2060 is a bit different there). 
Looks to me as though we should be able to get
away with a single ESP front end driver, perhaps set the DMA functions 
different based on the model?
