IIUC you do this to show the other buffer in the window above or on the
left and make sure that the buffer previously shown is not reshown.  I
don't understand yet whether you have problems when using
`sds-split-window' or whether `sds-split-window' avoids showing the same
buffer twice thus solving your problems.

Could you file a request at emacs-devel, explicitly stating that the
behavior you need was supported until Emacs 23.4 and is no more
supported in Emacs 24.1?  The appropriate patch would be similar to the
one you applied with the exception that the actual behavior would depend
on the value of a user option.
