The symbol you're having a problem with is resolved by tveeprom.ko.  That 
module needs to be loaded as well.  That module is provided both by the 
V4L core in the kernel tree and by ivtv.  It's possible that your kernel 
doesn't have tveeprom configured, but I would have expected ivtv to have 
it available.  So what you need to do is make sure tveeprom is loaded.  If 
it isn't, find out why.  I'm not familiar with a yum-based install of ivtv 
so I wouldn't know what to diagnose there.  But in any case the issue here 
is with tveeprom.ko.

The reason why I said you don't need the ivtv part of the pvrusb2 driver 
in this case is because those exact same modules (perhaps a different 
version however) are also supplied by ivtv.  If you have ivtv installed 
and working, then those modules should already be present, in which case 
the pvrusb2 driver can just use them directly thus no need to compile them 
from pvrusb2.
