I wanted to hold off until I was sure, but I've confirmed this was a
(second) hardware problem. Dell replaced my laptop's touchpad a second
time yesterday, and after deleting the device in Windows 10 and
refreshing, the OS detected the new touchpad fine. I reinstalled Ubuntu
yesterday and it's also working fine, with scrolling etc. functioning as
normal.

So basically, Dell gave me a laptop with a "broken hardware" touchpad
and improbably replaced it with a "bad firmware" touchpad. I appreciate
all the help with this issue, and I'll mark this bug resolved, and
update the other bugs.

Some takeaways:

1. Try other kernels / distros.
2. Try Windows (if available). Dual-boot would have been super handy in this 
case, even if the Windows installation is for break-glass emergencies.
3. Dell only replaces broken hardware with the same model as the original, so 
inconsistent hardware detection probably means bad hardware.
