It's probably one of the more challenging parts (along with getting the 
support upstream in the first place). It's something that is hard to 
solve in the other distro's too - RHEL for instance also has issues with 
the audio on the X1C7/X1C8 as it was upstream too late for their 8.2 
release (we've addressed it there with a Lenovo copr repository until 
it's accepted into RHEL). The balance between maintaining stability and 
cutting edge hardware is hard to solve.

That's where doing a Debian pre-load would be challenging (which is 
really where this conversation started). If support for a platform isn't 
there until 6 to 8 months after it's shipped (or more) then really it's 
not worth doing a preload (note - I'm not saying it's not worth 
supporting the platform - that is still important0. Fedora have this 
somewhat solved by being on the latest of everything, Ubuntu solve it by 
having their oem image model.

My naive aim starting to work with Debian was to get patches/fixes into 
sid and then figure out the rest from there - I tend to approach one 
hurdle at a time because my brain is too small to cope with more than 
that :) At least once it was in sid I could tell Debian users there was 
a way to get the fix on their platform (albeit with the stability risks 
- most users I have talked to seem OK with that). I'm wide open to 
suggestions on how to improve that or help/contribute towards improving 
that.
