The kernel has little information on what is what. For device it knows
the major number of the is requested. Now most of this is documented and
the latest modules-2.0.0 have most aliases done.

the second IDE interface is not a module and currently can't be setup
indenpendantly from ide0, so I guess this message will stay. You can do

alias block-major-22 off

to disable the message.

For binfmt, the same happen. Something is executable and the kernel does
