Sorry for not keeping up with your flow of ideas, so chiming in now:

I wonder if there is any way to set this where reiserfs assigns
the other ops.

I suspect many other ops aren't need either, but I really need input
from people that known reiserfs better.

I wonder if the is_bad_inode check should simplify move into
get/set_posix_acl.  But otherwise this patch looks good.
