acpi=force works! I first tried removing apmd, deleting apm in 
/etc/modules and adding acpi there. I also installed acpid and so on, 
but the machine complained of fatal errors, etc. So I uninstalled acpid, 
deleted acpi in /etc/modules and left just acpi=force in menu.lst -- and 
it worked.

So now I'm wondering how this works without the acpi module or having 
acpi compiled into the kernel. Does forcing acpi just makes it use the 
power management in the bios?

Thanks, gentlemen, for your kind assistance.
