"We have documented cases of humans leading normal lives with little to no brain beyond a cerebellum" -- I take this to mean that these are humans that have a cerebellum but not much else.

Your npr.org link talks about the opposite -- regular brain, but no cerebellum.

Your irishtimes.com link talks about cerebrum, which is not the same as cerebellum.

Your biology.stackexchange.com link talks about Cerebral Cortex, which is also not the same as cerebellum.

And the cbc.ca link does not contain the string "cere" on the page.

You're right - I mixed up cerebellum/cerebrum/cortex terminology. My bad. The cases I'm referencing are hydrocephalus patients with severely compressed cerebral tissue who maintained normal cognitive function. The point about structural variation not precluding consciousness stands."
