After checking the patch from yerstoday I have found that there is a 
small typo in
your IDE cleanup, which is causing oop es on my computer. The attached 
patch 5.1 is
fixing this. The attached patch 6 is combining everything and works fine 
for my computer.

Due to the need to debug this and to get 2.5.4 working at all, I wasn't 
unfortunately
able to do much more then analysis of the ide code. Apparently it's 
clear that
ide-tape, ide-cd and ide-floppy all could just be removed, if the IDE 
detection routines
would ignore atapi devices per defualt.
