Ok, so I took a long look at mv88e6xxx... and got it to work.

Good news is that modifications needed are not too heavy. Most are 
inlined below. (tag_daddr is still needed. I can send that too). 

Bad news is that only about half of all the registers are present on
6065 (6060 is similar), and I'm not sure how to do that
cleanly. Anything marked "W" is not present or reserved or different
in 6065. What would be good markup of registers that are common to all
and that are newer-generations-only be? Mark everything not present on
6065 as MV88E6085_*?

Is someone is interested in getting 6060 to work with mv88e6xxx?

Best regards,
									Pavel
