That's neither here nor there. If you don't think it matters, turn it off.
"Dell" bioses definitely do support APM. Perhaps not yours, but I know
people who have refused to upgrade to ACPI bioses because APM works very
well for them.

ACPI events are logged wherever you have them configured. Mine are, indeed,
all in /var/log/acpid (acpid must configure that itself, because I used to
get them in syslog). You should have events for every time you plug in the
AC and remove it, and for every time you open and close the lid. Those are
easy to check. You won't see an event for "shutdown", but you should see
power button events. However, I don't know about you, but with a stock
acpid I can't actually use the power button to wake my system with acpid
running - it immediately goes into shutdown mode.

I thought it had something to do with the values in /sys/power/state, but I
know that "echo 1 >/proc/acpi/sleep" works on my Dell. Haven't got anything
else working, yet.
