It's still there for the most part and were a good source of inspiration.

Those are probably still the same.

Yes that's about it. I also extended the bucts utility to support some
newer chipsets and report whether or not it can be set but that's not
really related to this.

Sadly those instructions did not lead to a successfully flashed thinkpad
for one user, so I'll investigate where the issue resides soon(ish).

Kind regards
