Not a problem, either. coreboot doesn't provide DMI (not needed).
That's not entirely true anymore. Nowadays Linux disables ACPI if DMI is not present. That results mostl likely in interrupts not working anymore.
Klaus, can you try acpi=force on the kernel command line and see if that helps?
I have a DMI implementation in one of my trees that will be merged with the next major patch.
