It's /proc/acpi/event.  If you don't have it, your problem is definitely not
ACPI related.  If you don't have it, you don't have ACPI.

Yes, you can't do a thing with it.  You need 'iasl' (should be available on the
ACPI sourceforge pages)

Not necessarily.  I have ACPI and haven't figured out how to get the power
management for kcontrol.

This _really_ sounds like BIOS level configuration.  Go into your BIOS settings
when you power-up, and look for anything that might be labelled "suspend",
"sleep" or "hibernate".  If you've got a system that goes into BIOS triggered
hibernation, that was intended to run with windows, a few people have
experienced major corruption when it proceeded to guess where the hibernate
partition was...

First, there is no such thing as "supposed to be" /proc/acpi/processor/0/info.
There _must_ be a /proc/acpi directory, to have acpi, and I think there probably
must be /proc/acpi/processor - though perhaps not. But the next level is named
in the BIOS, and could be anything,  The same with all directories under
/proc/acpi/*/.   However, if you are saying that you _do_ have
/proc/acpi/processor/0/info and it only contains "<TBD>", then I think you can
safely assume you don't have a proper ACPI BIOS.
