Ah, I didn't realize this wasn't a MacBook. We can't really hardcode values for
a Mac Pro since there isn't a fixed monitor resolution.

I did do a bit of digging into where these values could be found, and I
stumbled upon https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202730. OP
there had linked to
https://web.archive.org/web/20240703224557/https://ubuntuforums.org/showthread.php?t=1557326,
which contains a list of these values. But the MacPro3,1 listing there doesn't
match what OP got, probably because of a difference in monitor resolution.

We do attempt to work out these values later on in the function, and this seems
to work for OP in 202730, so either this has somehow regressed since then, or
it doesn't work for your configuration.

About installing a toolchain building FreeBSD, it should be fairly
straightforward if you're comfortable with the terminal. The build process is
documented in build(7).

> But do you think there are enough of them left to make it worth the time?
Kind of unrelated, but I find it funny that this concern was also mentioned
almost 11 years ago in the other PR.

These old Macs are getting rarer, yes. Whether or not fixing this is worth your
time is up to you. :)
