Actually, after thinking about it more, I seem to remember that Jason
Thorpe over in NetBSD runs an AS200 with a Promise Ultra/33 card.
So it might be an srm console issue with this card..  

Before pulling out all the stops, I'd first try updating the SRM
console, and they try a Promise card..

This is just a WAG though.
