I had this as wishlist because I didn't have that much time to work on
it until the release. But hardware support is "severity: important".

I have a merge request on salsa for x86 Chromebooks that has been open
for a while [2]. Please have a look. If you feel it'd be less work to
just do the changes yourself better than my attempt at it, please go ahead.
As I just commented on that MR: Chromebook user groups are distributing
ad-hoc custom kernel builds just because these aren't enabled in Debian
proper. I'd also like to get these enabled in stable after this, so
people can stop doing FrankenDebians for essential hardware support like
audio drivers.
I'll also look into configs needed for ARM Chromebooks in more detail,
but that'll take more time because more things were already-enabled on
the x86 side compared to the ARM side.
