Most shops I know of won't do it unless you are really good friends with a tech or something that would do it after hours, for liability reasons.  The dealership will most definitly not do it.  I don't know about another power steering pump... I will look into it when I get back from vacation, and since it is a mechanical pressure valve the computer will have no control over it.

sorry for all the no answers...

alright, alright. I was looking at the FAQ and it doesn't seem that hard, i guess. Is there anyone that could give me more detailed instuctions?
