Hi Marc,

Nice to see you again :)

I don't remember seing much posts about Itaniums since I'm here.

Step 1: find if you do have a SMBus PCI device. "/sbin/lspci | grep -i
smbus" should help.

Is it built into the kernel? You really need this, either in the kernel
or as a module, for sensors-detect to work properly.

My guess goes to a SMSC 47B27x. It isn't a full hardware monitoring
chip, but has Fan control capabilities.

I'll add detection support to sensors-detect, if you are willing to try
the updated version for confirmation.
