This was just partly correct. Coherent indeed run on PDP-11 (and not on 68k), but the PC version uses the very same bytesex as PDP-11 one, translating the byte order on the fly (_canl() routine defined in i386/as.inc file of Coherent 4.2.10 for i386 kernel is used).
Thus the mount option is really only useful with v7 filesystem and none of those handled with sysv filesystem.
