After the problem with UMSDOS and VFAT, I decided to reformat the disk
and just make a plain old FAT filesystem for UMSDOS to sit on (so it
could coexist with DOS and Windows 3.1 (useful for the people I'm setting
the machine up for). Instead of using DOS' "format" I decided to use
"mkdosfs" and it exited with no errors, but then when I tried to to
"mount -t msdos /dev/hdc1" I got:

VFS: Can't find a valid MSDOS filesystem on dev 16:01. mount: /dev/hdc1
not a mount point

Then I decided to turn the whole disk over to Linux, so I repartitioned
it and did

mke2fs -b 4096 -m 1 -v -c /dev/hdc1

mke2fs 0.5b, 14 -Feb-95 for EXT2 FS 0.5a, 95/03/19 104000 inodes, 103942

I tried "mke2fs" again and got the same message, and got an error when I
tried "mount" as well. The third time seemed to be the charm (no errors
when formatting, mounting, or while copying about 275 MB of files). Here
is what I've enabled in the kernel. No modules were loaded.
