I had the same problem replacing my old IDE DVD writer with an SATA 
writer. I also found the same solution.

On a similar note, my DVD burner died on my server so I temporarily 
replaced it with a CD-ROM drive I had lying around so I could boot the 
F8 rescue disk and install over FTP from my desktop. In this case when I 
replaced the CD-ROM with the burner from my desktop the drive was not 
detected at all. I have no idea how to force the detection so I copied 
the .rules file from my desktop which provided all the symlinks and such 
but replaced the address/bus info with what was in the .rules file on my 
server.

It did the trick but it seems strange to have such a problem detecting 
very standard hardware in a modern operating system.
