I think what's happening is that doc-view-mode is being run during file
autodetection, before the selected window switches to the doc-view
buffer.  Thus, (window-buffer (selected-window)) is not equal to
(current-buffer).

Maybe you could fix this by reinstating the variable
doc-view-current-page, which was removed in your 2008-02-21 change.
That would provide a "default" current-page, applicable when the buffer
isn't shown in any windows.  Then modify doc-view-display accordingly.
