Unfortunately I dont have either...
I know intel has a web page on the rz1000 chips..
and the current linux source code detects CMD640b and rz1000
and handles it... you might want to check it out.
Wish i could be of more help... I'd gladly try and write a aha driver based
off of the linux one, but unfortunately... I dont have the cash to afford a
plan 9 Cd. :)

Now if we could only figure out how to get the aic-7850's working with the
linux aic7xxx driver. :)
