See what the help button says, it usually includes information on which module
is build. (if the block one is loop.o it is the right one)

I think you did something wrong on the way, it should work without this

They have never severly done so for me, and I use them since I use Linux (ca 
4 years)

In your place, i would start over with the whole thing, rm everything thats 
related to kernel/module (i.e /lib/modules/<version> /usr/src/linux 
/modules.conf) reinstall kernel sources, reconfigure *slowly*, recompile with
make dep clean bzImage modules modules_install, recreate modules.conf, reboot 
and hope ;)
