This is exactly what I meant.  Sorry for being so distrait.

Not at all.  The problem is that `bury-buffer' (called from `next-buffer')
removes the buffer from the frame's buffer-list.  So a buried buffer is
no longer available from (frame-parameter nil 'buffer-list) for
`prev-buffer' called in the same frame after changing the order of
buried buffers in another frame.

Perhaps, there should be a separate list of buried buffers maintained
in a new frame parameter.
