OK, bit of progress:
the partition table has 32 entries, each 4 bytes long, apparently in little
from the Torch Triple-X (an earlier machine than the Quad-X I'm trying to get
running) manuals, there are four standard partitions - boot-loader, root, swap
and /usr, in that order. I don't yet know if that holds true of the QX, though.
I think what I was looking at before (when I saw the garbled filenames) was
the boot-loader partition; so it's possible that's only semi-compliant with SVR2.
I've managed to locate the offset to the root partition in the disk image, so
I can mount that - and surprise!, Linux will read it just fine, despite what
the Linux sysv filesystem docs say.
I still can't find where /usr starts on the disk, though, so I'm not quite
there yet - obviously I'm missing something and not quite decoding the
partition table right yet.
