 The SPARC LX in question is completely headless... no keyboard/monitor,
and no serial attached... only power, SCSI, and network... I am curious as
to when such changes took place in the kernel, as things were working as
expected with the 2.2.x kernels.

 Is this a new addition to the kernel for the 2.4.x series?

 Or, would you recommend any PROM settings I could set to get the current
default behavior of my LX to really power-off when I shutdown?
