The reason why that repository has no readme is because the Qubes master
repository has no readme. You do make a good point though:  All Qubes
packages should have some kind of write up on how to compile them. You
can kind of infer how to do it by reading through the Makefiles, but
still, it'd definitely be easier for anyone wanting to jump in to simply
test them, if not develop for them, if easier instructions were
available on how to compile them and what the software dependencies for
that repository are.

I did post some compile instructions in this thread here:

https://groups.google.com/d/msg/qubes-users/yBeUJPwKwHM/CFLgGsyKBAAJ

However, writing up a finalized and nicely formatted version for the
Qubes website is next on my TO-DO list.

As for things like Wacom tablets, I didn't mention it in my message in
this thread, but it, along with all other input devices supported in the
kernel, is still enabled in the current set of kernel options for this
version of the dom0 kernel. But if you were compiling this for yourself
and you don't use such devices, that's another category of kernel config
options that you could disable.

I've done some further refinement on my personal kernel, and it only
takes up around 50MB of disk space, down from about 200MB with the stock
kernel. And I still think it could be reduced even more. So the one
currently found in the repository definitely can still be cut down as
well, and there are probably some obscure kernel options that aren't
applicable to a dom0 kernel that I've missed.

You could probably go even further with a VM kernel. I simply no longer
have the time to test right now (and probably won't for a few months),
but some light testing on my end shows you can remove things such as
S/ATA support and native GPU drivers, simply because those aren't
normally needed in a VM environment (at long as you're not doing GPU
passthrough, although I don't know if that works with the open source
graphics drivers to begin with). A stripped down VM kernel would also
make for an interesting research project too.
