What is the guarantee that the names of these slots are correct and do

That would be a bug -- and yes, bugs happen, and we have to deal with
them.

My main concern is that BIOS vendors will not fix these bugs, as no
other OS cares/does this kind of thing today. The ammount of bad
information out there might be quite large, and I think this was
confirmed by some initial testing of IBM systems, right?

Yeah, but there's a flip side to this too: if no one uses the data, no one
will complain when it's wrong. If Linux starts making it easy to see this
stuff, there's a chance system vendors will start taking an extra 5 min.
before shipment to make sure that the BIOS info is up to date...

OTOH, I'm not sure which is worse, bad data or no data.
