> you absolutely can't trust them to write a kernel-mode driver without completely screwing everything up

Absolutely. The overwhelming majority of hardware companies are not competent enough to write drivers of any kind. They're not even competent enough to write user space software. They treat software as a cost center. To them software's just wasted money, to be made as cheaply as possible and only because they have to.

Linux kernel is great as a litmus test. If a company can't get a driver into the kernel it shouldn't be trusted with writing drivers of any kind.
