Usually this is caused by discover, which does automatic hardware detection, 
and these modules are needed for some older CD-ROMs, which cannot be detected 
by other means than loading all possible drivers and seeing, if the driver 
manages to detect a device.

Try removing discover (apt-get remove discover) and see if that fixes it. I 
have never really needed automatic hardware detection at boot or runtime, so 
I usually remove that as one of the first steps after install...
