Hi,
Believe it or not, I just implemented an SMBIOS implementation for coreboot in order to be able to use ACPI without acpi=force on the command line.
My DSDT in Asus A8V-E SE does not need any acpi=force option. All you need is to switch the PMIO block from legacy to ACPI mode in Coreboot. Please can you tell me more why you needed acpi=force?
