I can't help you I'm afraid but I think you're probably right to stick to
APM.  I have been running ACPI using acpi=force as a boot parameter,
(suggested in my dmesg), I thought it was a good thing that one or two
modules that would otherwise fail were now being loaded at boot-time, but
I have had the laptop overheat on me three times now!!! All ACPI seems to
do is shut your machine down _instantly_ before it burns up!  The fan
would run constantly or not at all depending on how hot it was at a reboot
and even when it was on, it whirred away at a steady but insufficient
speed to prevent the kernel from taking drastic action.  No to ACPI!  Not
on my Dell anyhow.


CC me by all means but a follow-up will usually do.
