/etc/sysconfig/modules/

[Sérgio Basto]

Hi,
In my F17 system  
rpm -qf  /etc/sysconfig/modules/*
bluez-4.99-2.fc17.x86_64 
qemu-system-x86-1.0.1-1.fc17.x86_64

on this 
http://fedora-os.org/2012/09/13/workaround-for-vbox-modules-loading/
Antonio Trande says that modules of vbox ( don't matter what) doesn't
load at boot time . 
But if this is true neither should boot bluez or qemu-system.
1 - Which package is responsibility to load modules
from /etc/sysconfig/modules/ ? 

2 - Also in article mention that we should put this files
in /etc/modules-load.d/ as part of systemd ,
but 
yum provides /etc/modules-load.d/\* 
No Matches found
shouldn't bluez, qemu-system-x86 etc etc  move loading modules
to /etc/modules-load.d/  ? 

Thanks,
