So, why don’t we have a separate kernel (a VM really) handling WiFi hardware and perhaps some other network stuff? For a laptop the overhead shouldn’t matter match.

Because that would take work; while you're at it why not switch to a decent microkernel and run all of these buggy-as-hell drivers in their own services. I have devices which I have 99% of the time on the kernel blacklist but enable when I need them as the system won't stay up reliably for more than a day or two with them enabled.

Thats what wifibox does on FreeBSD (though I believe the reason is more for drivers than for isolation): https://github.com/pgj/freebsd-wifibox
