If that worked for you you are lucky, but at least I won't flash a different
BIOS just to _downgrade_ my card, possibly breaking it completely. Alas the
already in place quirk results in exactly the same.

The new firmware files are fine for 370X it seems but still need work for 270X.
I guess most 270X users CC in this ticket will happily test possible reworked
ones as soon as they are available and we patiently wait for Alex.
