Whilst researching a bug in other packages and inspecting how fbdev
interacts with them I found the source package (.diff.gz) fetched with
dget contains the file

./revert-ae0aeffae665746.diff

It is not applied but as it changes a code path I'm inspecting closely I
thought to report and ask if there is some issue it is related to, since
that may inform my investigation into bug #1075713.
