Custom Override for DSDT?

[Matthew Tippett <matthew-+XluyfkzffvQT0dZR+AlfA@public.gmane.org>]

Getting back to the original question, would it make sense to support a 
way of overriding a dsdt to allow a broken BIOS that the manufacturer 
won't fix be usable?

This still keeps standards based ACPI compliance but with the nice twist 
  that we don't have to rely entirely on the manufacturer for the BIOS 
to work.

Regards,

Matthew
