It's true that you'd need drivers for your hardware, but that's not really special; I own plenty of normal x86 PCs with hardware that Linux doesn't have drivers for. That said, AIUI Google is generally pretty good at pushing drivers upstream these days. And the aftermarket UEFI is a great thing - it means that Chromebooks are probably the easiest+cheapest way to have a coreboot machine - but you don't actually need that; the default firmware will, in developer mode, boot any properly-formed image, which is a touch annoying but does in fact let you boot any OS that handles that boot system without replacing the firmware. One of my main machines right now is an ARM chromebook that runs postmarketos on the stock firmware.
