I suppose that makes sense and didn't think about it.  Moving detection code out 
of all modules into the main kernel would probably be alot of messy to deal with 
for embedded system builds.

Thanks I knew this, just hadn't noticed floppy was getting loaded (not that its 
hurting me).  A couple years ago I used to rebuild all the kernel rpms with my 
own moduleless config but haven't felt the need in a long time.
