Sorry - but DMI is all we've got.  We need to start using it, and have
people report bugs when it is wrong. Then it might get better. Linux
has had some success in shaming BIOS writers with:

 printk("Your BIOS is buggy ...")

Our biggest problem here is the life-cycle ... by the time Linux
users start seeing these problems, the BIOS people have already
moved on to the next generation system.

BUT - if Linux wants to play in RAS space - we need this to be
right - and to do that we need SMBIOS (DMI) bugs to be regarded as
priority #1.
