CentOS-4 uses a 2.6.9-x kernel that is much better at doing what your BIOS says for power saving mode than 2.4 kernels were. I would first check the sleep settings in the BIOS of the problem machine.
If that doesn't work, you try turning off the apmd and acpid services.
that unfortunately means teh system wont do a real poweroff if the UPS instructs it to.
dropped down to 2.4.31 kernel and the problem seems to have gone away so I think your right, its the 2.6.x kernel doing what it should, regrettably we dont want it to :)
What about changing the power-saving options in bios to do what you want?
