It is kind of interesting to see a part of my old thread(s)
resurrected, even if it isn't the part I was actually interested
in.
Note that my miniinfo email account no longer exists, but I
can still be reached at mmogilvi+q...@zoho.com if desired.
Regarding the patch, I haven't kept up with changes to qemu
well enough to really have a useful opinion, although superficially
it looks good. Perhaps it would make sense to include both
my old and new email addresses in the sign-off section, to both
tie it to the old threads and make it easier to reach me
if someone wants to contact me? (But I'm not sure of a "clean"
way to do so, and it is probably low priority. Perhaps this
current email is good enough?)

P.S.: Explanation and keywords to find this message (and me) with
search tools:
With regards to qemu, my primary interest (from that thread and
related 2012 threads) is/was being able to run
"Microport UNIX System V/386 v2.1" (ca. 1987) under qemu, which
especially required:
- Fixing various inaccuracies in qemu's model of the i8259
interrupt controller.
- Implementing very old graphics card model(s) that Microport UNIX
actually knows how to control properly. Perhaps original
IBM monochrome display adaptor (MDA), CGA, and/or hercules
graphics card. Or else my nasty qemu hackish patches I wrote
that allowed VGA to work in text mode despite Microport driving
it like CGA in a way that didn't work with real VGA hardware.
