And UEFI/ACPI currently appears to not give anyone anything
to support (yet).

to be fixed once driver support for the onboard networking is
added

(Jon is not always clear about UEFI/ACPI vs. U-Boot vs.
Linux kernel or whatever combination is involved.)

I've never been one to spend effort cutting things from
the standard kernels. In a couple of cases, in dealing
with old PowerMac issues, I've forced something to be
in the kernel to avoid contexts where I could not load
the same but it was always needed for what I was doing.

The PCIe slot has an Optane, not video. Very few of
the machines I use have video engaged even rarely.
One FreeBSD machine has a lower end (and low power)
video card --but I do not use X11 or the like on it
generally. Similarly for built-in HDMI (when it is
used at all).

The same Optane can be used to boot the MACCHIATObin
Double Shot, where it was previously in use. I do
not have access to other aarch64 machines with a
PCIe slot. These two machines only have one such
slot.
