You only need to 'modprobe cx88-dvb' - modprobe will automatically
load any other required modules.

Again, you only need to 'modprobe ivtv'

Newer versions of ivtv do not have the same limitation.

Yes, this was a problem a few years ago

You could try temporarily removing the kernel tveeprom file and
replacing it with that supplied with ivtv to work with both cx88-dvb
and ivtv. The ivtv 0.4.x tveeprom module was an adapted version of
that supplied with older kernels. Now that ivtv is in the kernel,
there are no such issues (See
http://ivtvdriver.org/index.php/Howto_legacy_ivtv).

Another way that was used in years past was to rename the ivtv files
and then alias the renamed ivtv-provided modules to names like
tveeprom-ivtv and tuner-ivtv in modprobe.conf. You could Google for
this - there are plenty of results.

If you have some degree of flexibility, you could upgrade your kernel
or distro - RHEL/CentOS5 to at least kernel 2.6.18. In my experience
you can expect to hit issues such as this using old kernels and
modules for video-capture, especially when some old versions of
modules contain forked versions of in-kernel modules.
