That version number is the version of the ACPI /proc/ interface, not the
exact driver version. That's current in the 2.4.18 kernel. You don't say
what kernel version you're using.

Do you have anything in /proc/acpi? Along with the event file, you
should have an info file, and a battery/ directory with a 0/ or 1/
subdirectory with files in it, and perhaps a similar thermal/ directory.

That doesn't sound like acpi is working on your system; it should be
able to power it down.

You might want to try the newer version of acpi in the 2.5 kernel
series, or from their website. You might first want to build a kernel
with acpi debugging turned on. Here is a good start for your kernel's
.config for acpi:

CONFIG_ACPI=y
CONFIG_ACPI_DEBUG=y
CONFIG_ACPI_BUSMGR=y
CONFIG_ACPI_SYS=y
CONFIG_ACPI_CPU=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_CMBATT=y
CONFIG_ACPI_THERMAL=y
