and the bad news is that it still doesn't work:
* "gmirror load" did create /dev/mirror/gm0{,a,b}, and it produced
no output on stdout or stderr, but it appended a couple of lines
to dmesg and the second does not look at all promising:
GEOM_MIRROR: Device mirror/gm0 launched (1/1).
GEOM_MIRROR: Cannot add disk ad0s2a to gm0 (error=17).
17 is defined in sys/errno.h as EEXIST /* File exists */
What can this mean? Of course ad0s2a and gm0 exist: ad0s2a is
the (so far only) provider for gm0, which was just instantiated.
By a different test, that error message may be bogus (long lines
reformatted):

This sure _looks_ as if mirror/gm0 and mirror/gm0a are seeing the
data on ad0s2a, so maybe it's working after all. But:
* After exiting from Fixit, and having sysinstall rescan devices so
as to become aware of /dev/mirror/gm0*, gm0 is not in the disk
list for either Partition (slice) or Label. I even tried:
Fixit# ( cd /dev && ln -s mirror/* . && ll gm* )
lrwxr-xr-x 1 root 0 10 Sep 6 10:48 gm0@ -> mirror/gm0
lrwxr-xr-x 1 root 0 10 Sep 6 10:48 gm0a@ -> mirror/gm0a
lrwxr-xr-x 1 root 0 10 Sep 6 10:48 gm0b@ -> mirror/gm0b
in case sysinstall looks only in /dev itself and not in any
subdirectories, and gm0 is *still* not in either list. How
do I get sysinstall to see it?
