OK, so at least the system switches off.

There's no much use for APM without it.

Enabling interrupts during APM calls.
Hmm, that's a clue, it's not a 12XL125. Could you try this patch to see if it works?

Could you also tell what the kernel thinks about your laptop? It should print things like "BIOS Vendor: Phoenix Technologies LTD".
