We don't have such a table. We support chips, not board or systems. You
may search the mailing-list archives or the support tickets:
http://secure.netroedge.com/~lm78/search.html
But I don't remember seing this family of servers discussed.

You may ask IBM directly, they are supposed to know what hardware is used
in their server boards. The hardware could be proprietary. Or they might
not be hardware monitoring stuff on these boards at all. What makes you
believe there is?

Not me. Of course, if you are willing to send me such a server for free,
I would take a look ;)

No, it should work just fine.

I don't think so.

If the Xeon have thermal sensors, sensors-detect should have seen them,
and the xeontemp driver as well. But I think I remember that not all
Xeon CPUs have the thermal sensors.

You can send us the full output of sensors-detect (after unloading all
i2c chip drivers) and we'll tell you if something can be done.
