I have no idea why you'd want to do that :) but you'll find that all the 
'File exist' ones were already included in your kernel.

'kldstat -v' will show all modules included in your (GENERIC?) kernel.

I'm not certain about the 'Exec format error' messages.

Then below are listed the modules loaded that weren't in your kernel.

Now showing all modules that were loaded in addition to those in kernel.  
Again, 'kldstat -v' will show all of them, with details of loaded ones.

cheers, Ian
