Doing a quick online search, this machine appears to be pretty old.  It
is possible that it does not support IPMI 1.5.  The output from
ipmi-locate you're seeing may be the defaults and not actual outputs
from the machine (this is confusing many people so I'm changing this
output for the next 0.9.1 release).  If it is only IPMI 1.0, there's
probably not much I can do to help you, since many of the IPMI commands
will just not be supported on your motherboard.

I assume you're using FreeIPMI 0.7.X b/c the newest one (0.8.X line)
does not have "[NA]" output.  There have certainly been fixes since
then, so you may wish to upgrade.  My initial guess was bridging, but
you seem to have tried that.

I've noticed on some motherboards that there are issues b/c I find
errors/problems in other parts of IPMI that ipmitool doesn't, thus I
output errors and they don't.  We need to dig into the core of the
errors on your board to figure out what they/I are doing
wrong/differently.  Can you provide --debug output?

Based on some of the error messages you posted from ipmitool (BTW, in
the future could you indicate what tools the error messages came from, I
thought you were indicating FreeIPMI errors and couldn't find them at
first), my guess is bridging is not supported on your motherboard and/or
there is a firmware issue w/ bridging, so the temp sensors can't be
reached.  It's hard to say.  If you can provide me --debug output from
ipmi-sensors, I can maybe analyze it deeper.

Does any HP specific software work for you for all these sensors?  If
their software does, and ipmitool/FreeIPMI does not, it indicates there
is something kooky on your motherboard.
