The second link, as well as the git repository, hasn't been updated for around 1 year
If you look at the diablo turbo thread, you'll see that we're stuck with an old kernel because it's too much work (impossible maybe?) to integrate the n8x0 bits in the mainline kernel, in part because, as the second link says "Diablo (Maemo OS 2008) user space components use non-standard kernel interfaces and most likely the interfaces are not acceptable to mainline. To get Diablo running with latest mainline kernels, this needs to be solved somehow. (You should consider instead looking for more recent systems, such as MeeGo.)"
Mmmmh
