I suspect that the kernel has acpi enabled. You can check by seeing

you will need to disable acpi. You do this by passing the argument
'acpi=off' to the kernel, either on the grub command line or in the
grub configuration file, /boot/grub/menu.lst. (I'm assuming that you
use grub; with lilo the procedure is similar.)
First. Thanks for your help so far.

Further to the last e-mail:

I removed apm using aptitude, it removed libapm0 and powermgmt-base as
well. Then I checked in my BIOS setup and there's no mention anywhere
of apm though acpi defaults to S1 (I think that's "shutdown" as opposed
to "sleep" or "suspend").

Yet I find in my log:

Aug 8 19:22:35 localhost kernel: apm: BIOS version 1.2 Flags 0x03 (Driver
version 1.16ac)
Aug 8 19:22:35 localhost kernel: apm: overridden by ACPI.
Aug 8 19:23:50 localhost kernel: apm: BIOS version 1.2 Flags 0x03 (Driver
version 1.16ac)
Aug 8 19:23:50 localhost kernel: apm: overridden by ACPI.

and apm.ko is at /lib/modules/2.6.8-3-k7/kernel/arch/i386/kernel/apm.ko .

Should it not have been removed with the other apm-related bits?

apm.ko is the kernel module which contains the APM routines. As such it
is part of the kernel-image-2.6.8-3-k7 package. Removing the apm daemon
and apm-related library/tools packages does not (and should not) result
in the removal of kernel modules.

The only thing in Control Centre under Power Control is Laptop
Battery. It reports:

Your computer seems to have a partial ACPI installation. ACPI was
probably enabled, but some of the sub-options were not - you need to
enable at least 'AC Adaptor' and 'Control Method Battery' and then
rebuild your kernel.

Should there be more under Power Control? If so, how do I get it there?

Try to modprobe "ac", "power" and "battery" and check if that makes any
difference.
