We do. Several of Sun's X64 rack servers use the service processor/console combo chip called AST-2100 and AST-2000. They have had this support for a while on the x86 side. At a time of pressure to control costs, why is this not common code? Why are we setting up a sparc branch and an existing x86 branch? Or are the two groups working together to merge this support in a common driver (add support for sparc to the existing x86 driver and place it in a common branch of the source tree)? > > 2) Does the driver support any power management features?
