As far as I can tell, this isn't near correct - according to all of the documentation I've read, the host ID should be calculated based on the machine type, and some portion of the MAC address.  This may be the wrong forum in which to ask this, but I'm wondering if someone could shed light on why it shows up that way, and if there's a way in OpenBIOS via the PROM/NVRAM data to set the host ID to something a little bit closer to normal?

The HOSTID used to have embedded knowledge about the system type and 
other details. As of (I recall) Sun4u, the hostid is 0x8000.0000 plus a 
serial number. Openbios should pick a number other than "0" for the 
serial number :-)
