mpt(4) controllers on sparc64

[Chris Ross <cross+netbsd%distal.com@localhost>]

  I recently obtained a LSI21320-R controller, and put it in my  
sparc64.  I added the mpt* line to my kernel, since AFAICT that was a  
MI driver, and when I reboot I see:

psycho1 at mainbus0 addr 0xfffc6000

  Anyone have any idea what's wrong here?  This is, by the way, a  
netbsd-5 kernel from a Jan 20 or so tree, so many recent changes may  
be missing.

  Thanks.
