You're right. I looked closer at the problem. It's this code:

   1689       if (!is_space_char (*l)
   1690           && *l != END_OF_INSN
   1691           && (intel_syntax
   1692               || (*l != PREFIX_SEPARATOR
   1693                   && *l != ',')))
   1694         {
   1695           as_bad (_("invalid character %s in mnemonic"),
   1696                   output_invalid (*l));

On sysv targets:

    211 #define PREFIX_SEPARATOR '\\'

Possibly --divide should alter the semantics in this case too. It's
something I need to bring up on the binutils list, but in the meantime,
it seems like a bug we have to work around.
