Thanks for your interest in OLPC firmware and software.

My bad.  The release notes for the firmware failed to describe fully
the nature of the added compatibility.  The compatibility is between
the firmware and a kernel in the boot-alt directory without device
tree support for dual core.  Without this change, the Q7C0x series
could not be used for a single core kernel.

Yes, 32013a4 and 32014a4 will fail to boot, that's expected.

Another developer has tried merging the kernel SMP patches with the
arm-3.5-android branch of the olpc-kernel git repository, but there
were regressions to fix, and they have not been solved.

There are no recent public hybrid builds.

The instructions for building will work on old hardware, but won't
work on XO-4 manufactured in 2015 and later, because a new kernel is
required.  The patches for this kernel are in the arm-3.5-android-4.x
branch of the olpc-kernel git repository.

I've used the instructions just last week to make my own hybrid build.

That's a wish for a change of software license conditions or the
underlying law.

It is more effective to build it yourself.

Doesn't this work already with the restricted software?
