Linux support is still basically non-existent for the first gen, and they made all this deal about supporting Linux and the open source community. This is to say, don't trust them

Clearly it's a priority because the support for ChromeOS/android support is a big headline this year.

Also worth noting that not all the bits needing support are inside of the Snapdragon, so specific vendor support from Dell, Lenovo etc is required.
Old situation: "Android drivers" are technically Linux drivers in that they are drivers which are built for a specific, usually ancient, version of Linux with no effort to upstream, minimal effort to rebase against newer kernels, and such poor quality that there's a reason they're not upstreamed.
New situation: "Android drivers" are largely moved to userspace, which does have the benefit of allowing Google to give them a stable ABI so they might work against newer kernels with little to no porting effort. But now they're not really Linux drivers.
In neither case does it really help as much as you'd hope.
