No BIOS Date for Acer T671 - no ACPI support

I don’t know why but ACER don’t bother putting dates or versions on the Phoenix/Award BIOS. This means SUSE 11 disables APM/ACPI and the start log says a acpi=force is required.

Using acpi=force stalls the machine early on boot and turning off acpi in the bios also gives errors. Has anyone had any luck in turning off a t671 using v11?
