Apparently the SC1435 does not have OpenManage. "Simple Computing" is
too simple to warrant that, I was told. They do have dset to look at
the  ESM logs but not for CentOS nor Fedora. Redhat is their
"validated" [sic] OS. That's the only one they support. So I'm sort of
stuck there.

I'll try ipmi. I was trying lm_sensors but apparantly it does not have
a driver for this chipset / motherboard combination. Not sure if its
an AMD Opteron specific driver issue or a
vendor-not-relesing-motherboard-specs issue (heard both versions on
the net). Anybody else had success using lm_sensors on the SC1435?
