Now you're moving on to why, which I think doesn't matter.
You asked what mess, I pointed out what I believed was the original
I don't really care why. Personally I also don't really think Linux
is a mess, I find it very structured, but like any modern operating
system the structure can seem really complex when starting out,
simply because there are so many components.

Not at all. If I was the one looking for the code that talks to
hardware I'd not only know where to find it, but I'd also know every
other component of hardware and software that the data passes through
on the way.

I think you may have missed my point. One part is certainly to know
how to find a file in a Linux system, but more important is the
question of what to search for (a file) and where to search (in the
kernel codebase). It's not at all obvious to a newcomer where the
kernel edge is, or even that the kernel is so distinct.

Getting to the point where one has a feel for the kernel's scope
already requires a bit of studying of the system.
I've had enough experience training my customers and on a couple
occasions also students to have seen many difficulties in grasping
exactly what the kernel is.

Hopefully the above explanation helps clarify that the problem is not
about finding "sprom" in the kernel source. At that point the problem
is, as you point out, quite easily solved. What can take a bit of
time is getting to the point of knowing where to search.

I think that would be a total micro-optimization for the case that I
have tried to describe. :\

It'll make you happy then that I'm happy to share what knowledge I
have. However, it's also important to choose one's battles, and I for
one prefer the lecture format in this case, if only because I can
speak faster than I can type. ;)
