That's probably just tweaking the kernel defconfig a bit more.

The panfrost changes for mesa are in guix since 1.2.0rc1, commit:

  ee401ed9249fbe284ef1b9b437d39207ca88131b

I think that bug report addressed multiple other issues, so didn't
exactly seem appropriate to close.

It has some history that makes rebasing complicated that I'd rather not
loose for now. When it's ready to merge to master, I'll go through the
trouble to rebase it.

I think the only things left are the 22 kernel patches in the
wip-pinebook-pro branch in
gnu/packages/patches/linux-libre-pinebook-pro-* ... many are flagged as
hacks in the comments and need to be re-implemented in a way that makes
the patches upstreamable... and then submitted upstream.

Might be able to further refactor those patches to get something useable
directly on guix master, but I haven't been comfortable pushing such
large changes to master (~2000 lines of code, ~3000 line kernel
config).

Although the patches are only applied to linux-libre-pinbook-pro and
shouldn't affect other packages at all...

There are also some changes (usb-c alternate display mode, wifi) that
may need to be removed for linux-libre; I believe linux-libre makes it
impossible to load the non-free firmware in practice, but the support
should just not be present at all.

The wip-pinebook-pro patches are stalled at 5.10, but at least 5.10 is a
long-term support kernel series:
