modprobe.d question

[Petrus de Calguarium <kwhiskerz gmail com>]

Recently, there have been loads of messages about the files in 
modprobe.d requiring .conf.

Now, for the most part, this has been resolved. Nevertheless, I 
notice that one such file remains on my system: blacklist-visor.  
It is dated 2008, although I have F11beta/rawhide. The file 
contains only the words 'blacklist visor'.

Has this file been obsoleted? Or will it be renamed with a .conf 
at some future point? Should I leave it and ignore the error 
messages, or can I delete it?
