I just upgraded from RH9 to FC4. The the distribution CDs I used
provided 2.6.11-1.1369_FC4.
The upgrade was successful and I was happy to see ACPI actually power
off my machine when I did a shut down. Something I had missed when I
went from XP to RH9.
My next step was to upgrade using yum. This jumped me to
2.6.17-1.2139_FC4. ACPI was now disabled in boot up.
After several days of poking araound doing before and after compares I
found something that works.
I added an acpi=force kernel parameter. ACPI loaded and shutdown now
powers off the box.
Yeah!
I spotted the work-around in another thread where it is used to get
around the ACPI BIOS age cutoff.
Not sure what happen after 2.6.11, though.
Does anyone care what happened? Should this be reported as a bug?
The motherboard, I am not sure what it is. The box is a HP Pavilion
9695C. The closest I can get to a specification for the motherboard is:

Here is a dmesg excerpt showing the dissabling message.
