The ivtv-users list is usually a very good source of relevant help:

If your old ivtv package is still available in your yum cache, you
could downgrade to it, but that might also mean moving to an earlier
kernel. The ivtv driver itself is in kernels 2.6.22+, so recent ivtv
packages contain additional helper modules.

I was fairly sure that the ivtv driver was in the kernel now which is why
my slave backend with two PVR-150s works without installing the ivtv
kernel module.  The strange thing is that my master backend will recognize
the pvr500 but will not be able to open it unless I have the current ivtv
kernel module installed from atrpms.  I will hit up the ivtv-users forum
and see if anyone has seen this before.
