    For instance:
    
     $ grep ^aes_x86 /proc/modules
     aes_x86_64 9056 2 - Live 0xffffffffa0091000
     $ l /lib/modules/2.6.31-tip/kernel/arch/x86/crypto/aes-x86_64.ko
     -rw-r--r-- 1 root root 136438 2009-09-22 19:05 /lib/modules/2.6.31-tip/kernel/arch/x86/crypto/aes-x86_64.ko
    
    Handle that by introducing a strxfrchar routine that replaces
    dashes with underscores when matching file names to loaded modules.
