The DSDT can't be updated without the BIOS being updated, and the DMI information gives us a BIOS version string that can be matched against if a fixed version is ever released. I'd be in favour of doing it with DMI on the grounds that it's how we already handle machine-specific quirks rather than adding new code to do it.
