I dug up the info but it's not in a form I'm willing to publishing.
However, someone did volunteer to look at this and I've provided them
with this info. So it will make into our CVS source tree and get
published that way.

Not AFAICT. PDC_CHASSIS is documented in the pdc32.pdf found on
	http://www.parisc-linux.org/documentation.html 

But my gut feeling is parisc specific code could make some PDC_CHASSIS
calls to set up "sysstat" field (eg initialize, shutdown, run states).

Does anyone know if the chassis codes used by HPUX are published?
It would be cool if parisc-linux used the same codes where possible...

Code I've looked at before seems to all do it in software.
